Anti-GRP78 Antibody, clone C38

The gene HSPA5 encodes a protein named GRP-78 (78 kDa glucose-regulated protein) also known as BiP (immunoglobulin heavy chain-binding protein) or heat shock 70 kDa protein 5. While originally discovered as one of set of genes that were induced upon cellular starvation and stress, HSPA5 encoded GRP-78 is now known to be an important member of the heat-shock family of proteins. The HSPA5 encoded GRP-78 protein appears to play a role in helping in the assembly of multimeric protein complexes in the endoplasmic reticulum (ER). Cellular localization is in the endoplasmic reticulum lumen and appears as cytoplasmic-like staining. The HSPA5 encoded protein is an essential component of the translocation processes within the endoplasmic reticulum and also functions in the retrograde transport across the ER membrane of incorrectly folded proteins destined to be degraded by the ubiquitin proteasome system. The HSPA5 encoded protein, while widely expressed in all cells types under normal conditions, is particularly induced under conditions of cellular stress, heat, or toxins and conditions which lead to the accumulation of unfolded proteins in the ER.
