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