Is predicted to encode a protein with the following domains: Staphylococcal nuclease homologue; Class II aldolase/adducin N-terminal; Staphylococcal nuclease (SNase-like), OB-fold; Class II aldolase/adducin N-terminal domain superfamily; Class II Aldolase and Adducin N-terminal domain; SNase-like, OB-fold superfamily; and Tudor domain. Is an ortholog of C. elegans
tsn-1. In C. elegans,
tsn-1 is involved in miRNA-mediated post-transcriptional gene silencing.
