Hspa5 Gene Summary [Rat]
Enables misfolded protein binding activity and unfolded protein binding activity. Involved in several processes, including cellular response to cAMP; cellular response to gamma radiation; and luteolysis. Acts upstream of or within response to endoplasmic reticulum stress. Located in several cellular components, including dendritic shaft; neuronal cell body; and smooth endoplasmic reticulum. Biomarker of metabolic dysfunction-associated steatohepatitis; post-traumatic stress disorder; steatotic liver disease; transient cerebral ischemia; and ureteral obstruction. Human ortholog(s) of this gene implicated in dopamine beta-hydroxylase deficiency. Orthologous to human HSPA5 (heat shock protein family A (Hsp70) member 5).

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 Hspa5 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
