Predicted to enable actin filament binding activity; collagen binding activity; and transmembrane signaling receptor activity. Acts upstream of or within several processes, including blood vessel development; negative regulation of extracellular matrix assembly; and positive regulation of metallopeptidase activity. Predicted to be located in external side of plasma membrane; filopodium membrane; and lamellipodium membrane. Predicted to be active in cell surface and plasma membrane. Is expressed in choroid plexus and lung. Human ortholog(s) of this gene implicated in GAPO syndrome and colorectal carcinoma. Orthologous to human ANTXR1 (ANTXR cell adhesion molecule 1).
