question:
Context: NADPH oxidase (Nox) family enzymes are one of the main sources of cellular reactive oxygen species (ROS), which have been shown to function as second messenger molecules. To date, seven members of this family have been reported, including Nox1-5 and Duox1 and -2. With the exception of Nox2, the regulation of the Nox enzymes is still poorly understood. Nox1 is highly expressed in the colon, and it requires two cytosolic regulators, NoxO1 and NoxA1, as well as the binding of Rac1 GTPase, for its activity. In this study, we investigate the role of the tyrosine kinase c-Src in the regulation of ROS formation by Nox1. We show that c-Src induces Nox1-mediated ROS generation in the HT29 human colon carcinoma cell line through a Rac-dependent mechanism. Treatment of HT29 cells with the Src inhibitor PP2, expression of a kinase-inactive form of c-Src, and c-Src depletion by small interfering RNA (siRNA) reduce both ROS generation and the levels of active Rac1. This is associated with decreased Src-mediated phosphorylation and activation of the Rac1-guanine nucleotide exchange factor Vav2. Consistent with this, Vav2 siRNA that specifically reduces endogenous Vav2 protein is able to dramatically decrease Nox1-dependent ROS generation and abolish c-Src-induced Nox1 activity. Together, these results establish c-Src as an important regulator of Nox1 activity, and they may provide insight into the mechanisms of tumor formation in colon cancers. 
 Question: Which NADPH oxidase family member requires interaction with NOXO1 for function?
answer:
nadph oxidase 1

Context: Linda Westinghouse [Ewa Stromberg], a lawyer with the Istanbul firm of Simpson & Sons, is sent to Anatolia to handle the inheritance of Countess Nadine Carody, recipient of the entire estate of Count Dracula of Hungary. To Linda's surprise, Nadine [Soledad Miranda] is the strange woman who has been haunting her dreams for the past several weeks. Nadine is also a vampire and, after sharing a swim, a glass of wine, and some kisses, Nadine bites Linda's neck and drinks some of her blood. When Linda comes to and goes in search of Nadine, she finds her floating in the swimming pool, apparently dead. The next thing Linda knows, she is being treated at Dr Aldon Seward's clinic, bewildered as to how she got there and amnesic as to her name and address. Dr Seward [Dennis Price] puts a notice in the newspaper, which brings Linda's boyfriend Omar [Andres Monales] looking for her. Linda remembers Omar but still remembers nothing that went on at Countess Carody's beachhouse. Her only memory is of the Countess lying dead in the swimming pool and then being alone at sea. She wonders if it was all a dream.However, Nadine is not dead. She is languishing on a couch, telling her renfield Morpho [Jose Martinez Blanco] how she became a vampire (Dracula saved her from being raped and initiated her into the secret of the vampires) and how she now hates men and is so infatuated with Linda that she must make Linda into a vampire, too. Hearing Nadine calling to her, Linda goes. Nadine drinks a bit more of Linda's blood. Later, Linda consults with Dr Seward who tells her that, if she wishes to extract herself from the spell of the vampire, she must either split the vampire's head with an axe or pierce it with a pole.Meanwhile, one of Dr Seward's patients, Agra [Heidrun Kussin], who has been alternately babbling about the Queen of the Night (Nadine) coming to see her and then abandoning her, now suddenly announces that the Queen is going to come to the sanitarium to meet Seward. Nadine shows up at the sanitarium, angry with Seward for trying to take Linda away from her. Seward admits that he only did it to get Nadine to come to him. He wants to become initiated into the world of the vampires. When Nadine refuses and Seward starts shouting Latin at her, Nadine gets Morpho to kill Seward while she pays a visit with Agra in order to tell her that she's going to leave her again.Meanwhile, Linda goes missing. Omar enlists the help of Linda's shrink, Dr Steiner [Paul Muller], in tracking down Nadine in hopes of finding Linda. Actually, Linda is being held by Memmet [Jesus Franco], the bellboy at her hotel. Turns out Memmet was Agra's husband before she became bewitched by Nadine. Memmet has fallen for Linda and wants to kill her, but Linda kills him first and then escapes. Steiner and Omar go to Nadine's house in Istanbul, but she and Morpho have returned to their beachhouse in Anatolia. Linda goes there, too. She finds Nadine lying in bed, dying. Nadine begs Linda for some blood, but Linda doesn't want to be under Nadine's power and stabs her through the eye. Nadine's body disappears. Morpho kills himself. Omar and Steiner arrive on a boat. Omar tries to convince Linda that it was all a dream, but Linda knows better. [Original Synopsis by bj_kuehl.]

Context: This article's plot summary may be too long or excessively detailed. Please help improve it by removing unnecessary details and making it more concise. (March 2010) (Learn how and when to remove this template message) On March 17, 994 A.D., The Leprechaun is a thousand years old. Since that is his birthday, he can choose any woman to be his bride. He picks a young girl of the O'Day family. The Leprechaun describes the girl he has chosen to O'Day, but when O'Day sees that the girl is in fact his daughter, he intervenes with "God bless you, my child" therefore denying the Leprechaun his bride, as the creature can marry any girl who sneezes three times, provided no one says "God bless you." The Leprechaun captures, tortures and tells O'Day that he will marry his descendant in a thousand years time on St Patrick's Day, before he kills O'Day, whose corpse is then discovered by his daughter. One thousand years later, St Patrick's Day 1994, in modern-day Los Angeles, the Leprechaun has found a petulant sixteen-year-old girl named Bridget Callum, a descendant of the O'Day bloodline, who has got into a fight with her boyfriend, Cody Ingalls. Cody, whose legal guardian is his uncle, Morty, frequently has to break their dates in order to support Morty, an alcoholic scam artist. The Leprechaun steals some whiskey and a gold tooth from a homeless man and a gold ring off the finger of Tim Streer, a talent agent, who believes that the little man is some kind of performer. After all of this, he follows Bridget to her house, where a boy named Ian attempts to persuade her into letting him in; she refuses with a swift elbow to his ribs. The Leprechaun then creates an illusion that fools Ian into believing that Bridget is asking him to kiss her big breasts, while in actuality, they are a pair of lawnmower blades that start up after Ian shoves his face into them. Shortly afterwards, Cody knocks on the door and apologizes, offering flowers, which causes Bridget to sneeze all over his shirt. The third time she sneezes, Cody begins to say "God bless you," but is unable to complete the blessing when the Leprechaun attempts to strangle him with a telephone cord. After a struggle, the Leprechaun grabs Bridget and disappears, losing one of his gold coins, which Cody soon finds. The police soon arrive, find Bridget missing, Ian dead, and a note from Cody at the scene, leading them to get an arrest warrant out for him. Cody returns to Morty's house and tells him what happened; Morty says he's crazy until the Leprechaun breaks into the house and they barely escape. Morty and Cody then go to a bar, which is filled with little people dressed as leprechauns, celebrating St. Patrick's Day. While there, Cody is given a piece of chocolate in a gold wrapper by one of the bar's patrons (Tony Cox). The Leprechaun appears and Morty challenges him to a drinking contest in honor of his wedding. While the Leprechaun downs whiskey, Morty is actually drinking soda and water. The Leprechaun eventually becomes extremely drunk, so much to the point he can barely speak properly or use his magic. He distracts Morty and Cody by turning on a jukebox with his powers, leading him to bash Morty in the head with a bottle to get away. He goes to a coffee shop, where he sobers up, and takes the time to murder a waiter (Michael McDonald) who was making jokes about his size and speech. Upon being asked for payment for the coffee, the leprechaun thinks the waiter wants to take his gold and kills him. Meanwhile, Cody and Morty break into the go-kart racetrack that Ian worked at since the office contains a huge safe on wheels made of wrought iron, the only thing that can harm the Leprechaun. Cody traps the Leprechaun inside, but Morty takes advantage of the opportunity to claim three wishes and locks Cody in a store room. His first is for the Leprechaun's pot of
