Predicted to enable metal ion binding activity. Predicted to be an extracellular matrix structural constituent. Acts upstream of or within several processes, including animal organ development; embryonic limb morphogenesis; and roof of mouth development. Located in basement membrane. Is expressed in several structures, including alimentary system; body cavity or lining; brain; sensory organ; and skin. Used to study Fraser syndrome and clubfoot. Human ortholog(s) of this gene implicated in Fraser syndrome 1. Orthologous to human FRAS1 (Fraser extracellular matrix complex subunit 1). [provided by Alliance of Genome Resources, Apr 2022]
