WH1 domain is an evolutionary conserved protein domain.
 Therefore, it has an important function.
 WH1 domains are found on WASP proteins, which are often involved in actin polymerization.
 Hence, WH1 is important for all cellular processes involving actin, this includes cell motility, cell trafficking, cell division and cytokinesis, cell signalling, and the establishment and maintenance of cell junctions and cell shape.
Kenneth Michael Benbow "Kenny" Blank (born September 15, 1977) is an American actor and musician.
 Later, he changed his name to Kenn Michael.
 Blank is best known for his role as Michael Peterson in the television series "The Parent 'Hood" from 1995 to 1997 for which he also composed some music, as well as his appearance in Eddie Murphy's 1992 film, "Boomerang".
Precision bombing refers to the attempted aerial bombing of a target with some degree of accuracy, with the aim of limiting collateral damage.
 An example would be destroying a single building in a built up area causing minimal damage to the surroundings.
 Precision bombing was initially tried by both the Allied and Central Powers during World War I, however it was found to be ineffective because the technology did not allow for sufficient accuracy.
 Therefore, the air forces turned to area bombardment, which inevitably brought about civilian casualties.
 "Precision bombing" was notably attempted by the United States Army Air Forces over Europe during World War II, as it was believed that heavy bombers could accurately bomb targets from high altitude using the Norden bombsight.
 Since then, the development and adoption of guided munitions has greatly increased the accuracy of aerial bombing.
 Because the accuracy achieved in bombing is dependent on the available technology, the "precision" of precision bombing is relative to the time period.
The Anti-Imperialist Cell (German: "Antiimperialistische Zelle", AIZ) was a leftist militant group responsible for bombing attacks in Germany in 1995, and other killings.
 The group was formed believing itself to be the successor of the Red Army Faction.
 The cell is responsible for an attempted bombing that was foiled when police stopped their car, but when searched the explosives had vanished.
 Threats were made against the ruling political parties of Germany by the group.
 The group is responsible for a failed bombing at Free Democratic Party offices, a bombing of a German office in Peru, a bombing of a German Chancellor's home, a failed bombing of another German politician's home, and a bombing of a German ex-minister's home (no one was harmed).
 The two members of the group, Bernhard Falk and Michael Steinau, were arrested in February, 1996.
 After these arrests, the AIZ actions ceased.
Kenneth Michael Trentadue (December 19, 1950 – August 21, 1995) was an American citizen who was found hanged in his cell at FTC Oklahoma during the investigation of the Oklahoma City bombing.
 His death was officially ruled a suicide three years after it occurred.
 Trentadue's family maintains that he was murdered by members of FBI who mistakenly believed he was involved in the Oklahoma bombing and that officials at the prison engaged in a cover-up.
 Oklahoma City's chief medical examiner said of Trentadue that it was "very likely he was murdered".
 Timothy McVeigh stated that he believed Trentadue was mistaken for Richard Lee Guthrie Jr., a suspected co-conspirator in the bombing who also died in federal custody, allegedly from suicide by hanging.
There are three different types of basic cell communication and they are: surface membrane to surface membrane, exterior, which is between receptors on the cell, and direct communication, which means signals pass inside the cell itself.
 The junctions of these cells is incredibly important because they are the means by which cells communicate with one another.
 Epithelial cells especially rely on these junctions because when one is injured, these junctions provide the means and communication to seal these injuries.
 These junctions are especially present in the organs of most species.
 However, it is also through cell signaling that tumors and cancer can also develop.
 Stem cells and tumor-causing cells, however, do not have gap junctions so they cannot be affected in the way that one would control a typical epithelial cell.
 Upstream cells signaling pathways control the proteins and genes that are expressed, which can both create a means for cancer to develop without stopping or a means for treatment for these diseases by targeting these specific upstream signaling pathways.
 Much of cell communication happens when ligands bind to the receptors of the cell membrane and control the actions of the cell through this binding.
 Genes can be suppressed, they can be over expressed, or they can be partially inhibited through cell signaling transduction pathways.
 Some research has found that when gap junction genes were transfected into tumor cells that did not have the gap junction genes, the tumor cells became stable and points to the ability of gap junction genes to inhibit tumors.
The sarcoplasmic reticulum (SR) is a membrane bound structure found within muscle cells, that is similar to the endoplasmic reticulum in other cells.
 The main function of the SR is to store calcium ions (Ca).
 Calcium ion levels are kept relatively constant, with the concentration of calcium ions within a cell being 100,000 times smaller than the concentration of calcium ions outside the cell.
 This means that small increases in calcium ions within the cell are easily detected and can bring about important cellular changes (the calcium is said to be a second messenger; see calcium in biology for more details).
 Calcium is used to make calcium carbonate (found in chalk) and calcium phosphate, two compounds that the body uses to make teeth and bones.
 This means that too much calcium within the cells can lead to hardening (calcification) of certain intracellular structures, including the mitochondria, leading to cell death.
 Therefore, it is vital that calcium ion levels are controlled tightly, and can be released into the cell when necessary and then removed from the cell.
The cluster of differentiation (also known as cluster of designation or classification determinant and often abbreviated as CD) is a protocol used for the identification and investigation of cell surface molecules providing targets for immunophenotyping of cells.
 In terms of physiology, CD molecules can act in numerous ways, often acting as receptors or ligands (the molecule that activates a receptor) important to the cell.
 A signal cascade is usually initiated, altering the behavior of the cell (see cell signaling).
 Some CD proteins do not play a role in cell signaling, but have other functions, such as cell adhesion.
 CD for humans is numbered up to 371 (s of 2016 ).
Timothy James McVeigh (April 23, 1968 – June 11, 2001) was an American domestic terrorist convicted and executed for the detonation of an ammonium nitrate fertilizer and nitromethane truck bomb in front of the Alfred P. Murrah Federal Building in Oklahoma City on April 19, 1995.
 Commonly referred to as the Oklahoma City bombing, the attack killed 168 people and injured over 600.
 According to the United States government, it was the deadliest act of terrorism within the United States prior to the September 11 attacks, and remains the most significant act of domestic terrorism in United States history.
Kenneth Michael "Mike" Conaway ( ; born June 11, 1948) is the U.S. Representative for Texas 's 11th congressional district , serving since 2005.
 He is a member of the Republican Party.
 The district is located in West Texas and includes Midland, Odessa, San Angelo, Brownwood and Granbury.
 Conaway was asked to lead the investigation into Russian interference in the 2016 United States elections (with assistance from Trey Gowdy and Tom Rooney) after the Intelligence Committee chair, Devin Nunes, recused himself.
