RNA-binding protein that acts as a translational repressor. When overexpressed, able to disperse P-bodies. Interacts with ribonucleoprotein complex components. Interacts with cpeb. Oocyte-specific protein. Expressed throughout oogenesis but is not detectable in eggs, embryos, nor in adult tissues (at protein level). Already expressed in the smallest stage I oocytes. Then it decreases during oocyte growth until stage VI (at protein level). Belongs to the PAT1 family.
