Hspa2 Gene Summary [Rat]
Enables protein-folding chaperone binding activity and tau protein binding activity. Predicted to be involved in several processes, including negative regulation of inclusion body assembly; positive regulation of ATPase-coupled calcium transmembrane transporter activity; and protein folding. Predicted to act upstream of or within several processes, including male meiosis I; positive regulation of G2/M transition of mitotic cell cycle; and synaptonemal complex disassembly. Predicted to be located in cell surface; meiotic spindle; and nucleus. Predicted to be part of CatSper complex. Predicted to be active in cytosol; nucleus; and plasma membrane. Orthologous to human HSPA2 (heat shock protein family A (Hsp70) member 2). [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 rat Hspa2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
