Efemp2 Gene Summary [Rat]
Predicted to enable heparin binding activity and protein homodimerization activity. Predicted to be involved in several processes, including negative regulation of vascular associated smooth muscle cell proliferation; positive regulation of aortic smooth muscle cell differentiation; and vasculature development. Predicted to act upstream of or within artery development and elastic fiber assembly. Predicted to be located in basement membrane; elastic fiber; and microfibril. Biomarker of osteoarthritis. Human ortholog(s) of this gene implicated in aortic aneurysm; arterial tortuosity syndrome; autosomal recessive cutis laxa type IB; endometrial cancer; and osteosarcoma. Orthologous to human EFEMP2 (EGF containing fibulin extracellular matrix protein 2). [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 Efemp2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
