Is predicted to encode a protein with the following domains: SPRY domain; P-loop containing nucleoside triphosphate hydrolase; Concanavalin A-like lectin/glucanase domain superfamily; AAA domain; SAP domain; and B30.2/SPRY domain superfamily. Is an ortholog of C. elegans tofu-2. In C. elegans, tofu-2 is involved in primary piRNA processing.
