RNA-binding factor that positively regulates gene expression by prohibiting miRNA-mediated gene suppression. Relieves miRNA repression in germline cells. Prohibits the function of several miRNAs by blocking the accessibility of target mRNAs. Sequence-specific RNA-binding factor that binds to U-rich regions (URRs) in the 3'untranslated region (3'-UTR) of several mRNAs. Does not bind to miRNAs. May play a role during early embryonic survival (By similarity). Perinuclear germ granules, also called germ plasm or chromatoid body. Expressed in germ cells; along the cleavage planes at the vegetal pole of early cleavage stage embryos.
