Description

General description

HSP90AB1 (heat shock protein 90α family class B member 1) belongs to the Hsp90 family. It consists of major members-Hsp90α, Hsp90β, GRP94 (glucose-regulated protein 94) and Hsp75. It is located on chromosome 6p21. HSP90AB1is an ATP-dependent molecular chaperone, having a molecular weight of 90kDa. HSP90AA1 is located on human chromosome 14q32.31.

Specificity

The antibody is reactive with both the constitutive and the inducible forms of HSP90. However, it does not bind to the native form of HSP90. It does not recognize HSP90 from E. coli and yeast.

Immunogen

heat shock protein 90 (HSP90) from the water mold Achlya ambisexualis

Biochem/physiol Actions

HSP90AB1 (heat shock protein 90α family class B member 1) participates in signal transduction, protein folding and degradation, and morphological evolution. It is required for the transport of client proteins between the cytoplasm and nucleus. In lung adenocarcinoma patients, overexpression of HSP90AB1 in non-small cell lung cancer tissues results in imperfect clinical predictions. Suppression of this gene reduces the potential of endothelial cells to form tube structures.
