Verville VCP

The Verville VCP was an American single-engined biplane fighter aircraft of the 1920s. A single example of the VCP-1 was built by the United States Army Air Service's Engineering Division, which was later rebuilt into a successful racing aircraft, while a second, modified fighter was built as the PW-1.

Design and development

VCP-1

In 1918, Virginius E. Clark, in charge of the Plane Design section of the U.S. Army Air Service's Engineering Division and Alfred V. Verville, who had recently joined the Engineering Division from private industry, started design of a single-seat fighter (known as "pursuit" aircraft to the U.S. Army), the VCP-1 (Verville-Clark Pursuit).

Drawing from the experience of the French and their SPAD S.XIII, the desire was to make a sleeker and more maneuverable fighter. The VCP-1 was powered by a Wright-built 300 hp (220 kW) Hispano-Suiza 8 V-8 engine and had tapered single-bay biplane wings. The fuselage was a monocoque structure constructed of plywood, while the wings were of wood and fabric construction. The engine was cooled with an unusual annular radiator.

Valosin-containing protein

Transitional endoplasmic reticulum ATPase (TER ATPase) also known as valosin-containing protein (VCP) or CDC48 in S. Cerevisiae is an enzyme that in humans is encoded by the VCP gene. The TER ATPase is an ATPase enzyme present in all eukaryotes and archaebacteria. Its main function is to segregate protein molecules from large cellular structures such as protein assemblies, organelle membranes and chromatin, and thus facilitate the degradation of released polypeptides by the multi-subunit protease proteasome.

p97/CDC48 is a member of the AAA+ (extended family of ATPases associated with various cellular activities) ATPase family. Enzymes of this family are found in all species from bacteria to humans. Many of them are important chaperones that regulate folding or unfolding of substrate proteins. p97/CDC48 is a type II AAA+ ATPase, which means that it contains two tandem ATPase domains (named D1 and D2, respectively) (Figure 1). [[File:VCP Wiki Figure 1.jpg|thumb|A schematic diagram of the p97 domain structure.]] The two ATPase domains are connected by a short polypeptide linker. A domain preceding the D1 domain (N-terminal domain]]) and a short carboxyl-terminal tail are involved in interaction with cofactors. The N-domain is connected to the D1 domain by a short N-D1 linker.
