RNA-binding protein required during male meiosis and development of the syncytial embryo (PubMed:17951964, PubMed:19631203, PubMed:30772175). Binds poly-(A) tails of mRNAs and regulates their expression by regulating their stability or translation (PubMed:17951964, PubMed:19631203). Interacts with pAbp. At the end of embryogenesis, accumulates in the gut and muscles. Phosphorylated on threonine and serine residues (PubMed:30772175). During oogenesis, phosphorylation on Ser-1119 by Pink1 at the outer membrane of defective mitochondria, impairs its ability to promote local translation and mtDNA replication thus reducing transmission of deleterious mtDNA mutations to the mature oocyte (PubMed:30772175). Mutant males show multiple meiotic phenotypes such as a failure of chromosome segregation, cytokinesis and mitochondrial partition. Defects in spindle pole organization and spindle formation. Mutant-derived syncytial embryos show a range of mitotic phenotypes, including failure of centrosomes to migrate around the nuclear envelope, detachment of centrosomes from spindle poles, the formation of multipolar spindle arrays and cytokinetic defects. Unusual initiator. The initiator methionine is coded by a non-canonical ATA isoleucine codon. Truncated N-terminus. Unusual initiator.
