Model of AMX-1 in sterility compared with SPR-5. AMX-1 and SPR-5 function in both redundant and non-redundant manners. In wild-type animals, both AMX-1 and SPR-5 are necessary for proper fertility and sterility and maintenance of H3K4me2 level. While spr-5 sterility does not require p53/CEP-1, amx-1 sterility requires p53/CEP-1. AMX-1 modulates the adequate expression of Piwis in a CEP-1-dependent manner; thus, the absence of AMX-1 expression results in sterility. AMX-1 and SPR-5 are necessary for ICLR and DSBR, respectively.
