Is required for meiosis completion in both male and female germ cells. Confers stability to numerous meiotic mRNAs in gonads allowing proper initiation and progression into meiosis prophase I. The function may involve YTHDC2 and is independent of induction by retinoic acid (RA). Maintains an extended meiotic prophase I by properly promoting the transition from a mitotic to a meiotic cell cycle program by binding transcripts through its interaction with YTHDC2 that regulate the mitotic cell cycle. Interacts with YTHDC2; binds transcript that regulate the mitotic cell cycle inhibiting progression into metaphase, thereby allowing meiotic prophase to proceed normally. at late pachytene a fraction is nuclear. Expressed in fetal ovaries (PubMed:26742488). Expressed in testis (PubMed:28380054). Expression first detected in wpf (week post-fertilization) 11 and is highest in wpf 22.
