General description

Heat shock cognate 71 kDa protein (UniProt P19120; also known as Heat shock 70 kDa protein 8, HSC70, HSC71, HSC73) is encoded by the HSPA8 (also known as HSC70, HSC73) gene (Gene ID 281831) in bovine species. The mammalian HSP70 family consists of the mitochondrial HSP75, the endoplasmic HSP78, the cytoplasmic HSC70 (a.k.a. HSC73 and HSP73) and its inducible counterpart HSP72 (a.k.a. HSP70). The latter two have similar structures and properties, and both of them bind misfolded, newly synthesized polypeptides in an ATP-dependent manner, reflecting their chaperonic activity. All cells constitutively express HSC70. On the other hand, the expression of HSP72 in normal cells is mainly stress inducible, although constitutively high HSP72 expressions are observed in malignant human tumors of various origins. The induced HSP72 expression enables stressed cells to better cope with the elevation of unfolded/denatured proteins and prevent apoptosis under various stress conditions.

Specificity

Clone N69 reacts with the constitutively expressed HSPA8/Hsc70 (HSC73), but not the heat schock-inducible HSP72 (Demidov, O.N., et al. (1999). Eur. J. Cardiothorac. Surg. 16(4):444-449).

Immunogen

Co-purified Hsc73 and Hsp72 proteins from bovine skeletal muscle.
