Enriched in reproductive tract based on proteomic studies. Is predicted to encode a protein with the following domains: MFS transporter superfamily; Ankyrin repeats (3 copies); Ankyrin repeat; Ion channel regulatory protein, UNC-93; Ion channel regulatory protein UNC-93; Ankyrin repeat-containing domain superfamily; BRCT domain superfamily; and Zinc finger, RING/FYVE/PHD-type. Is an ortholog of C. elegans unc-93. In C. elegans, unc-93 is involved in regulation of muscle contraction and regulation of potassium ion transport.
