Is predicted to encode a protein with the following domains: F-box-like domain superfamily; B30.2/SPRY domain superfamily; F-box domain; SPRY domain; and Concanavalin A-like lectin/glucanase 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 positive regulation of neuromuscular synaptic transmission.
