Enables collagen binding activity. Involved in several processes, including smooth muscle cell migration; smooth muscle cell-matrix adhesion; and wound healing, spreading of cells. Acts upstream of or within several processes, including collagen-activated tyrosine kinase receptor signaling pathway; mammary gland development; and neuron projection development. Located in plasma membrane. Is expressed in several structures, including central nervous system; future hindbrain; genitourinary system; mammary gland; and retina. Human ortholog(s) of this gene implicated in lung non-small cell carcinoma. Orthologous to human DDR1 (discoidin domain receptor tyrosine kinase 1).
