Enriched in germ line based on microarray studies. Is predicted to encode a protein with the following domains: Triose-phosphate Transporter family and Sugar phosphate transporter domain. Is an ortholog of C. elegans sqv-7. In C. elegans, sqv-7 is involved in several processes, including egg-laying behavior; proteoglycan biosynthetic process; and pyrimidine nucleotide-sugar transmembrane transport.
