Predicted to enable cell adhesion molecule binding activity and myosin binding activity. Predicted to be involved in cell-cell adhesion. Predicted to act upstream of or within excretion; negative regulation of protein phosphorylation; and positive regulation of actin filament polymerization. Located in cell projection membrane; cell-cell junction; and membrane raft. Human ortholog(s) of this gene implicated in nephrotic syndrome type 23. Orthologous to human KIRREL1 (kirre like nephrin family adhesion molecule 1). [provided by Alliance of Genome Resources, Apr 2022]
