Hspa1a Gene Summary [Mouse]
Enables protein folding chaperone. Involved in lysosomal transport and protein folding. Acts upstream of or within DNA repair; response to heat; and telomere maintenance. Located in cytoplasm. Is expressed in several structures, including adrenal gland; crista ampullaris; early conceptus; genitourinary system; and vibrissa. Human ortholog(s) of this gene implicated in several diseases, including Kawasaki disease; autoimmune disease of musculoskeletal system (multiple); cystic fibrosis; schizophrenia (multiple); and vascular dementia. Orthologous to human HSPA1A (heat shock protein family A (Hsp70) member 1A). [provided by Alliance of Genome Resources, Jul 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 Hspa1a often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
