NCIt synonyms : GRP 78 Protein; Heat Shock 70 kDa Protein 5; Immunoglobulin Heavy Chain Binding Protein; Immunoglobulin Heavy Chain-Binding Protein; BiP Protein; Endoplasmic Reticulum Lumenal Ca(2 )-Binding Protein grp78; BiP; GRP78; HSPA5; GRP78 Protein;
NCIt definition : 78 kDa glucose-regulated protein (654 aa, 72kDa) is encoded by the human HSPA5 gene.
The protein is intracellularly localized in the endoplasmic reticulum lumen, and plays
a role in the assembly of multimeric protein complexes inside the organelle. In addition,
the protein is thought to function as a pro-survival protein, or an inhibitor of apoptosis.;
