Is predicted to encode a protein with the following domains: Switch protein XOL-1, N-terminal; Ribosomal protein S5 domain 2-type fold, subgroup; Switch protein XOL-1, GHMP-like; GHMP kinase, C-terminal domain superfamily; and Ribosomal protein S5 domain 2-type fold. Is an ortholog of C. elegans
xol-1. In C. elegans,
xol-1 is involved in dosage compensation by hypoactivation of X chromosome; intergenic mRNA trans splicing; and male sex determination.
