Is predicted to encode a protein with the following domains: PH-like domain superfamily; Phosphatase 4 regulatory subunit 3; Domain of unknown function DUF625; and Armadillo-type fold. Is an ortholog of C. elegans smk-1. In C. elegans, smk-1 is involved in several processes, including defense response to bacterium; negative regulation of mitotic DNA damage checkpoint; and response to radiation.
