Predicted to enable signaling receptor binding activity. Acts upstream of or within several processes, including cell-cell adhesion; fin morphogenesis; and regulation of basement membrane organization. Predicted to be located in basement membrane; extracellular region; and membrane. Is expressed in several structures, including axial mesoderm; nervous system; pectoral fin bud; pericardial region; and pharynx. Human ortholog(s) of this gene implicated in bent bone dysplasia syndrome 2 and familial nephrotic syndrome. Orthologous to human LAMA5 (laminin subunit alpha 5).
