Binding immunoglobulin protein (BiPS) also known as 78 kDa glucose-regulated protein (GRP-78) or heat shock 70 kDa protein 5 (HSPA5) is a protein that in humans is encoded by the HSPA5 gene. BiP is a HSP70 molecular chaperone located in the lumen of the endoplasmic reticulum (ER) that binds newly … See more BiP contains two functional domains: a nucleotide-binding domain (NBD) and a substrate-binding domain (SBD). The NBD binds and hydrolyzes ATP, and the SBD binds polypeptides. The NBD consists … See more The activity of BiP is regulated by its allosteric ATPase cycle: when ATP is bound to the NBD, the SBDα lid is open, which leads to the … See more BiP’s ATPase cycle is facilitated by its co-chaperones, both nucleotide binding factors (NEFs), which facilitate ATP binding upon ADP release, and J proteins, which promote ATP hydrolysis. BiP is also a validated substrate of HYPE (Huntingtin Yeast Interacting … See more • HSPA5+protein,+human at the U.S. National Library of Medicine Medical Subject Headings (MeSH) • Human HSPA5 genome location and See more When K12 cells are starved of glucose, the synthesis of several proteins, called glucose-regulated proteins (GRPs), is markedly increased. GRP78 (HSPA5), also referred to as … See more BiP is highly conserved among eukaryotes, including mammals (Table 1). It is also widely expressed among all tissue types in … See more Autoimmune disease Like many stress and heat shock proteins, BiP has potent immunological activity when released from the internal environment of the … See more WebJul 6, 2010 · In a dynamic equilibrium, binding to unfolded proteins pulls Ire1 into oligomeric clusters and away from the chaperone BiP.
