Description

Description générale

78 kDa glucose-regulated protein (UniProt: P11021; also known as GRP-78, Endoplasmic reticulum lumenal Ca(2+)-binding protein grp78, Heat shock 70 kDa protein 5, Immunoglobulin heavy chain-binding protein, BiP) is encoded by the HSPA5 (also known as GRP78) gene (Gene ID: 3309) in human. GRP78 a member of the HSP family of molecular chaperones that is required for stress-induced autophagy and for endoplasmic reticulum (ER) integrity. GRP78 is involved in multiple processes, including translocation of the newly formed proteins across the ER membrane, folding and assembly of proteins, and targeting misfolded proteins for ER-associated degradation. It plays a critical role in regulating unfolded protein response (UPR). Following ER stress, GRP78 is released from ER transmembrane signal transducers, such as PKR-like ER kinase (PERK), which leads to the activation of UPR signaling pathways. Once GRP78 is dissociated, PERK is allowed to dimerize and is autophosphorylated and activated. Activated PERK phosphorylates elF2alpha that results in the reduction of protein synthesis.
