An extracellular matrix structural constituent. Acts upstream of or within cellular response to amino acid stimulus; collagen-activated tyrosine kinase receptor signaling pathway; and extracellular matrix organization. Located in basement membrane. Part of collagen type IV trimer. Is expressed in several structures, including bone; meninges; oral region epithelium; sensory organ; and trunk. Human ortholog(s) of this gene implicated in AMME complex and X-linked deafness 6. Orthologous to human COL4A6 (collagen type IV alpha 6 chain). [provided by Alliance of Genome Resources, Apr 2022]
