Cytoplasmic poly(A) RNA polymerase that adds successive AMP monomers to the 3'-end of specific RNAs, forming a poly(A) tail. Acts as a regulator of mitosis/meiosis required for progression through meiotic prophase during oogenesis and spermatogenesis and for promotion of the entry into meiosis from the mitotic cell cycle. May act by regulating and activating gld-1 mRNA activity in germ line.
