Enriched in reproductive tract based on proteomic studies. Is predicted to encode a protein with the following domains: WD40 repeat; WD40/YVTN repeat-like-containing domain superfamily; and WD40-repeat-containing domain superfamily. Is an ortholog of C. elegans
atg-18. In C. elegans,
atg-18 is involved in several processes, including determination of adult lifespan; gamete generation; and xenophagy.
