Apoa5 Gene Summary [Rat]
Predicted to enable several functions, including cholesterol transfer activity; enzyme activator activity; and heparin binding activity. Involved in animal organ regeneration; lipid transport; and response to hormone. Located in extracellular space. Biomarker of hypothyroidism. Human ortholog(s) of this gene implicated in cerebral infarction; coronary artery disease; familial hyperlipidemia (multiple); and type 2 diabetes mellitus. Orthologous to human APOA5 (apolipoprotein A5). [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 Apoa5 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
