MRNAs that co-purify with OMA-1 in the C. elegans germline (sequencing)

ABSTRACT: The oocytes of most animals arrest at diplotene or diakinesis, but resume meiosis (meiotic maturation) in response to hormones. In C. elegans, maturation of the –1 oocyte requires the presence of sperm, Gas-adenylate cyclase-PKA signaling in the gonadal sheath cells, and germline function of two Tis11-like CCCH zinc-finger proteins, OMA-1 and OMA-2 (OMA proteins). Prior studies indicate that the OMA proteins redundantly repress the translation of specific mRNAs in oocytes (zif-1, mom-2, nos-2, glp-1) and early embryos (mei-1). We purified OMA-1-containing ribonucleoprotein particles (RNPs) and identified mRNAs that associate with OMA-1 in oocytes using microarrays. We examined the relative abundances of mRNAs in OMA-1 RNPs using high-throughput RNA sequencing. Previously identified targ
