Hspa9 Gene Summary [Rat]
Enables fibroblast growth factor binding activity; heat shock protein binding activity; and protein-folding chaperone binding activity. Involved in several processes, including calcium import into the mitochondrion; cellular response to interleukin-1; and response to thyroxine. Located in mitochondrial matrix. Biomarker of Parkinsonism and brain ischemia. Human ortholog(s) of this gene implicated in Parkinson's disease and autosomal dominant sideroblastic anemia 4. Orthologous to human HSPA9 (heat shock protein family A (Hsp70) member 9). [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 rat Hspa9 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
