Predicted to enable integrin binding activity. Predicted to be an extracellular matrix structural constituent. Predicted to be involved in several processes, including cell morphogenesis involved in differentiation; integrin-mediated signaling pathway; and morphogenesis of a polarized epithelium. Predicted to act upstream of or within several processes, including animal organ development; cilium assembly; and protein localization to plasma membrane. Part of laminin-5 complex. Orthologous to human LAMA5 (laminin subunit alpha 5). [provided by Alliance of Genome Resources, Apr 2022]
