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; Synaptotagmin, SMP domain; C2 domain superfamily; and Synaptotagmin-like mitochondrial-lipid-binding domain. Is an ortholog of C. elegans esyt-2.
