HSP90AB1 (he at shock protein 90 αfamily 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.
