RNA-binding protein, which is required during gametogenesis. May be involved in the actin-dependent anchoring of Vg1 mRNA in the vegetal cortex of the oocyte. Component of a mRNP complex, at least composed of DAZAP1, IGF2BP3-A, STAU and VgRBP60. Binds to the 3'-UTR of Vg1 mRNA. Interacts with profilin, a protein involved in actin assembly. Interacts with VgRBP71. Concentrated in the vegetal cortex of stage III/IV oocytes. Expressed in oocytes. Expressed gradually during oogenesis. First expressed in stage I-II oocytes at a low level. Strongly expressed during stage III-IV, and thereafter for the remainder of oogenesis.
