Is predicted to encode a protein with the following domains: F-box-like domain superfamily; F-box domain; Concanavalin A-like lectin/glucanase domain superfamily; and B30.2/SPRY domain superfamily. Is an ortholog of C. elegans fsn-1. In C. elegans, fsn-1 is involved in several processes, including determination of adult lifespan; negative regulation of neuron projection development; and regulation of cell communication.
