Hsp90ab1 Gene Summary [Mouse]

Enables protein folding chaperone; protein kinase binding activity; and tau protein binding activity. Contributes to protein kinase regulator activity. Involved in several processes, including cellular response to heat; chaperone-mediated protein folding; and negative regulation of proteasomal protein catabolic process. Acts upstream of or within cellular response to interleukin-4; negative regulation of apoptotic process; and placenta development. Located in growth cone; neuronal cell body; and perinuclear region of cytoplasm. Part of HSP90-CDC37 chaperone complex. Is expressed in several structures, including branchial arch; central nervous system; eye; jaw; and limb. Human ortholog(s) of this gene implicated in multiple sclerosis. Orthologous to several human genes including HSP90AB1 (heat shock protein 90 alpha family class B member 1). [provided by Alliance of Genome Resources, Apr 2025]

Protein Domains

A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Hsp90ab1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
