CELE_F10B5.5, F10B5.5

pch-2 encodes a putative AAA+-type ATPase orthologous to budding yeast PCH2 and human TRIP13 (OMIM:604507); PCH-2 is required for the apoptosis of pachytene cells induced by unsynapsed chromosomal pairing centers, but is dispensable for meiotic apoptosis induced by DNA damage; PCH-2-mediated apoptosis is inhibited by SYP-1 and SYP-2, while it requires HIM-8 (and probably HIM-8's paralogs, ZIM-1/-3 and C02F5.12); however, PCH-2-mediated apoptosis does not require SPO-11; pch-2 transcripts are enriched during oogenesis; the excess germline apoptosis of syp-1(me17) mutants is partially suppressed by pch-2(tm1458), and fully suppressed by pch-2(tm1458);spo-11(ok79).
