Col4a3 Gene Summary [Mouse]
Predicted to enable integrin binding activity. Predicted to be an extracellular matrix structural constituent conferring tensile strength. Involved in cell surface receptor signaling pathway; glomerular basement membrane development; and negative regulation of angiogenesis. Acts upstream of or within collagen-activated tyrosine kinase receptor signaling pathway. Located in basement membrane. Part of collagen type IV trimer. Is expressed in several structures, including cardiovascular system; central nervous system; foregut; genitourinary system; and sensory organ. Used to study autosomal recessive Alport syndrome. Human ortholog(s) of this gene implicated in Alport syndrome; autosomal dominant Alport syndrome; autosomal recessive Alport syndrome; benign familial hematuria; and end stage renal disease. Orthologous to human COL4A3 (collagen type IV alpha 3 chain). [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 mouse Col4a3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
