Is predicted to encode a protein with the following domains: Type I membrane glycoproteins cell-cell fusogen; Cell-cell fusogen EFF/AFF, domain 3; and Cell-cell fusogen EFF/AFF. Is an ortholog of C. elegans
eff-1. In C. elegans,
eff-1 is involved in several processes, including anatomical structure morphogenesis; egg-laying behavior; and pharyngeal muscle development.
