Epas1

Enables DNA-binding transcription activator activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and protein heterodimerization activity. Involved in mRNA transcription by RNA polymerase II; myoblast fate commitment; and positive regulation of cold-induced thermogenesis. Acts upstream of or within several processes, including multicellular organismal-level iron ion homeostasis; norepinephrine metabolic process; and surfactant homeostasis. Located in cytoplasm and nuclear speck. Part of transcription regulator complex. Is expressed in several structures, including alimentary system; cardiovascular system; genitourinary system; nervous system; and respiratory system. Used to study newborn respiratory distress syndrome. 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, Jul 2025]

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 mouse 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.
