Is predicted to encode a protein with the following domains: PTB domain (IRS-1 type); Staphylococcal nuclease (SNase-like), OB-fold; SNase-like, OB-fold superfamily; Staphylococcal nuclease homologue; Tudor domain; and IRS-type PTB domain. Is an ortholog of C. elegans
tsn-1. In C. elegans,
tsn-1 is involved in miRNA-mediated post-transcriptional gene silencing.
