Predicted to enable semaphorin receptor binding activity. Is an ortholog of C. elegans smp-1. In C. elegans, smp-1 is involved in nematode male tail mating organ morphogenesis.
Is predicted to encode a protein with the following domains: C2 domain superfamily; C2 domain; Synaptotagmin-like mitochondrial-lipid-binding domain; and Synaptotagmin, SMP domain. Is an ortholog of C. elegans esyt-2.
