Epas1 Gene Summary [Rat]

Enables DNA-binding transcription factor activity and cobalt ion binding activity. Contributes to sequence-specific DNA binding activity. Involved in several processes, including norepinephrine biosynthetic process; positive regulation of dopamine biosynthetic process; and regulation of transcription by RNA polymerase II. Predicted to be located in cytoplasm and nuclear speck. Predicted to be part of transcription regulator complex. Used to study acute kidney failure and intermittent claudication. Biomarker of artery disease (multiple); bronchopulmonary dysplasia; glucose metabolism disease (multiple); polycystic kidney disease; and renal cell carcinoma. Human ortholog(s) of this gene implicated in familial erythrocytosis 4; lung non-small cell carcinoma; polycythemia; and pulmonary hypertension. Orthologous to human EPAS1 (endothelial PAS domain protein 1). [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 Epas1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
