HSPA5 - heat shock protein family A (Hsp70) member 5 Gene
Also Known as BIP; GRP78; HEL-S-89n
Species: Homo sapiens
About HSPA5
This gene has 15 transcripts (splice variants), 248 orthologues and 13 paralogues. Broad expression in thyroid (RPKM 442.6), bone marrow (RPKM 284.6) and 24 other tissues.
Summary
The protein encoded by this gene is a member of the heat shock protein 70 (HSP70) family. This protein localizes to the lumen of the endoplasmic reticulum (ER) where it operates as a typical HSP70 chaperone involved in the folding and assembly of proteins in the ER and is a master regulator of ER homeostasis. During cellular stress, as during viral Infection or tumorogenesis, this protein interacts with the transmembrane stress sensor proteins PERK (protein kinase R-like endoplasmic reticulum kinase), IRE1 (inositol-requiring kinase 1), and ATF6 (activating transcription factor 6) where it acts as a repressor of the unfolded protein response (UPR) and also plays a role in cellular Apoptosis and senescence. Elevated expression and atypical translocation of this protein to the cell surface has been reported in viral infections and some types of Cancer cells. At the cell surface this protein may facilitate viral attachment and entry to host cells. This gene is a therapeutic target for the treatment of coronavirus diseases and chemoresistant cancers.
