Endoplasmin (UniProt P14625; also known as 94 kDa glucose-regulated protein, Endothelial cell (HBMEC) glycoprotein, Epididymis luminal protein 35, Epididymis secretory sperm binding protein Li 125m, gp96 homolog, GRP-94, Heat shock protein 90 kDa beta member 1, Stress-inducible tumor rejection antigen gp96, Tumor rejection antigen 1) is encoded by the HSP90B1 (also known as ECGP, GP96, GRP94, HEL35; HEL-S-125m, TRA1) gene (Gene ID 7184) in human. The endoplasmic reticulum (ER) chaperone Grp94 mediates the cell surface export of molecules involved in the native immune response, mesoderm induction, muscle development, cytoprotection against oxidative stress, and calcium homeostasis. Src family tyrosine kinase Fyn-catalyzed Grp94 phosphorylation is reported to be essential for Grp94 export from ER to the Golgi apparatus in the early phase of myoblast differentiation.
Synonyms: Endoplasmin, 94 kDa glucose-regulated protein, GRP-94, Heat shock protein 90 kDa beta member 1, GRP94
