# Protein pigeon homolog

Protein pigeon homolog also known as gamma-secretase activating protein (GSAP) is a protein that in humans is encoded by the PION gene.

## Gene

The human PION gene is located on the long (q) arm of chromosome 7 at band 11.23, from base pair 76,778,007 to base pair 76,883,653. Highly conserved PION orthologs have been identified in most vertebrates for which complete genome data are available. More distantly related orthologs are also expressed in insects including the pigeon gene in Drosophila melanogaster that when mutated produces the "pigeon" phenotype. The name of the human PION gene derives the corresponding Drosophila gene.

## Protein

The transcribed human pigeon homolog protein is 854 amino acid residues in length. A 16 kDa fragment (GSAP-16K) derived from 121 residues from the C-terminus region of the full length protein is known as the γ-secretase activating protein (GSAP).

## Function

γ-secretase activating protein (GSAP) increases β-amyloid production through a mechanism involving its interactions with both γ-secretase and its substrate, the amyloid precursor protein (APP). By binding to both the γ-secretase enzyme and its APP substrate, GSAP increases the affinity and the selectivity of the enzyme for this particular substrate.

## Therapeutic target for Alzheimer's disease

The activating function of GSAP can be inhibited by the anticancer drug imatinib (Gleevec) which in turn prevents γ-secretase from converting APP into plaque forming β-amyloid without affecting the other functions of γ-secretase. Imatinib itself does not get into the brain so imatinib could not be used as an AD therapeutic. However it may be possible to identify imatinib-like drugs that do get into the brain. Hence GSAP represents a potential therapeutic target for the treatment of Alzheimer's disease (AD).
The drug semagacestat in contrast to imatinib, works by directly inhibiting the γ-secretase. While semagacestat reduces β-amyloid plaque formation in AD patients, γ-secretase is also needed to make other important proteins. The failure of semagacestat to improve the cognitive function of AD patients may be due to its non-selective blockade of γ-secretase. The more selective blockade of γ-secretase provided by inhibiting GSAP may make GSAP a more efficacious and safer drug target than γ-secretase.

## Discovery

The PION gene was originally discovered through a large scale genome sequencing effort. However the function of the PION gene product remained a mystery. In the laboratory of Paul Greengard, a screen of compounds that could inhibit the formation of β-amyloid identified imatinib, however it was not immediately known how it accomplished this. Later it was discovered by Greengard's lab that imatinib inhibited the function of GSAP and that GSAP in turn functions as an activator of γ-secretase.

# Lilius (crater)

Lilius is a lunar impact crater that is located in the rugged southern highlands of the Moon. It lies to the north of the crater Zach, and south-southwest of Cuvier. Just to the southeast is the slightly larger Jacobi. The crater is named after the inventor of the Gregorian calendar, Aloysius Lilius.
The outer rim of Lilius has been worn down and rounded, particularly to the northwest where the inner wall protrudes farther into the interior floor. The lowest portion of the rim is to the south, adjacent to a crater attached to the southeast part of the outer wall. The interior floor is relatively flat and featureless, but there is a wide, domed central peak at the midpoint.

## Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Lilius.

# Olli Saarela

Olli Juhani Saarela (born 16 March 1965) is a Finnish film director. He has directed films such as Ambush, Bad Luck Love, Rollo and the Woods Sprite and Year of the Wolf, which is based on a book written by Virpi Hämeen-Anttila. Ambush was entered into the 21st Moscow International Film Festival.

## Family

On 21 May 2006 Saarela married Tanja Karpela (née Vienonen, 2006–2008 Saarela), who was then the Minister of Culture in Finland and was Miss Finland in 1991. Their marriage ended up in divorce in 2008.
Olli Saarela was in relationship with actress Jenni Banerjee after his marriage with Tanja Karpela. Banerjee and Saarela separated in early 2012. Now Olli Saarela is living with actress Jenny Rostain.

## Education and career

Before Saarela started studying to become a film director, he worked as a firefighter.

## Production company and soundtracks

MRP Matila Röhr Productions is the production company that has produced most of Saarela's films. Tuomas Kantelinen created the soundtracks to Saarela's films.

## The Heinäluoma incident

In August 2006, Saarela directly attacked Minister of Finance Eero Heinäluoma in an interview for Image Magazine, since, in his opinion, the Social Democratic Party of Finland that Heinäluoma heads had slandered his wife during budget negotiations. Minister of Culture Tanja Saarela ended up having to explain her husband's comments to the press and Olli Saarela later apologized for his rash comments.
   That a grown man dares to. He's a miserable, big and bald-headed sissy. I would've punched him in the nose, the way he made himself look good was so outrageous.

# One Single Tariff

One Single Tariff (official name "Single Communication Tariff Act") is a European Citizens' Initiative against roaming in Europe. One Single Tariff's precise objective is to erase all barriers to phone calls within the EU by ending all roaming fees. It is the second European Citizens' Initiative to have been registered, on May 10, 2012, just one day after the initiative Fraternité 2020, which was presented by the European Commission on Europe Day. To be successful, it had to collect 1 million signatures before December 3, 2013, but it failed.

## Background

Although the EU has built an integrated Single Market at the continental level, phone companies still mainly operate at the individual state level. Regulations are passed by the European Union but so far a discrimination remains between consumers in the EU. Regulations are passed by the European to cap these fees, without banning them entirely.

## Founders

The initiative was founded by Vincent Chauvet, former Thomson Reuters journalist in Brussels, while in his last year of study at HEC Paris and SciencesPo, and Martin Wittenberg, communication consultant, former ALDE staff member and embedded correspondent to the campaign of Barack Obama in 2008.

## Supporters

The initiative is supported, amongst others, by members of the European Parliament like Jean-Luc Bennahmias, Alain Lamassoure and the President of the European Economic and Social Committee Henri Malosse.

## Responses

Following the launch of this initiative, the Benelux announced it would end roaming barriers between Luxembourg, Belgium and the Netherlands. In reaction, it has been reported that telecom operators were mulling pooling infrastructure to create a new common entity that could be used on a wholesale basis by all companies, thus creating a common roaming tariff. In June 2013, Neelie Kroes announced she supported One Single Tariff aim and that she would propose it by Summer 2013.

# Ontario Highway 667

Secondary Highway 667, commonly referred to as Highway 667, is a provincially maintained secondary highway located in the Sudbury District of the Canadian province of Ontario. Roughly 35 kilometres (22 mi) in length, the route connects Highway 129 to the town of Sultan and to Wakami Lake Provincial Park. East of the town, the route continues as the Sultan Industrial Road, a privately maintained but publicly accessible logging road, towards Highway 144. Highway 667 was established in 1977 and has remained unchanged since then.

## Route description

Highway 667 begins at Highway 129 near the entrance to Five Mile Lake Provincial Park. The highway travels southeast for 14 kilometres (8.7 mi), crosses Little Wenebegon Lake then curves to the east. It is mostly straight from that point to its eastern terminus at the Sultan Industrial Road, passing clear cut forests along the way. The road which carries Highway 667 continues east into Sultan as a local street.
Like other provincial routes in Ontario, Highway 667 is maintained by the Ministry of Transportation of Ontario. In 2016, traffic surveys conducted by the ministry along the route showed that on average, 180 vehicles used the highway daily.

## History

Highway 667 was established along an existing forest access road in 1977. The route was originally unpaved. Since then, it has been paved, but otherwise remains unchanged.

## Major intersections

The following table lists the major junctions along Highway 667, as noted by the Ministry of Transportation of Ontario. The entire route is located in Sudbury District.

| The Penguin Guide to Jazz Recordings | |
In his review for AllMusic, Scott Yanow states "This music will take a bit of patience but it is worth the time for Ellman's music is quite original and subtle."
The All About Jazz review by Mark F. Turner notes "The creative and exhilarating Ophiuchus Butterfly finds Ellman digging deeper into eccentric and progressive territories with a sextet of like-minded artists with distinct voices."
In a review for PopMatters, Will Layman says "Ophiuchus Butterfly is reserved in its solo statements, but exuberant in its rhythms and construction."
The JazzTimes review by Aaron Steinberg states "Ellman still likes his funk and bop, but he’s now thinking in bigger structures, more complicated voicings and in textures."

# Operation ROBOT

Operation ROBOT was an economic policy devised by HM Treasury in 1952 under Chancellor of the Exchequer R. A. Butler but which was never implemented. It was named after three of its civil servant advocates, Sir Leslie ROwan, Sir George BOlton and OTto Clarke.
During the winter of 1951–52 in Britain there was anxiety over the balance of payments and the reduction of Britain's gold reserves. R. A. Butler, the Chancellor, advocated floating the exchange rate and allowing sterling to find its own level and to be convertible. Butler acknowledged that his proposals would end the Keynesian full employment policies of the previous twelve years but claimed that the burden would fall not on Britain's precarious gold reserves but on the exchange rate. British exports would become cheaper, imports would become more expensive, food prices would rise, as would the prices of raw materials and possibly unemployment would also rise under the scheme. Clarke claimed that a free exchange rate would be 'painful' but would impose severe discipline upon British industry because of its exposure to the world markets.
The most prominent of those who urged for its rejection were a Treasury under-secretary, E. R. Coplestone, and Lord Cherwell, the Paymaster General. Cherwell argued that unemployment would rise to one million and inflation could increase if the plan was implemented. He also argued that it would be political suicide, which would end in disaster. Both the Governor (Lord Cobbold) and the deputy governor (Sir George Bolton) of the Bank of England, as well as the Colonial Secretary Oliver Lyttelton, were in favour of implementing it.
In February 1952 the Cabinet rejected it as too risky.
# Orchard Road (song)

"Orchard Road" is a song by Leo Sayer released in February 1983 as the second single from his tenth album Have You Ever Been in Love. It peaked at number 16 on the UK Singles Chart, becoming his final top-twenty hit until his 2006 feature on "Thunder in My Heart Again".

## Release and composition

The music for "Orchard Road" was composed by Alan Tarney, with the lyrics by Sayer. Tarney, who also produced the song, had previously worked with Sayer producing his 1980 album Living in a Fantasy, which included the top-ten hit "More Than I Can Say".
According to Sayer, the lyrics to the song are based on an all-night phone conversation out in a public telephone booth he had with his then-wife, Janice, pleading for her return from her flat and forgiveness after a lapse of judgement in their 7-year marital life. In reality, the song refers to Churchfield Road, Acton in Greater London where his wife had moved out to. However, the name "Churchfield Road" "didn't sing very well", so it was changed to "Orchard Road", the name coming from the shopping area in Singapore as Sayer had recently performed there.
The song was originally recorded in one take as a demo, with Sayer "[making] up the words as we recorded it, with Alan Tarney playing to my hand signals". However, the demo became the final version with the slightly unpolished guide vocal kept due to how it felt.
