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 germline. ATP + RNA(n) = diphosphate + RNA(n)-3'-adenine ribonucleotide Interacts with gld-3. Germline-specific. Abundant in embryos, fourth larval stages and adults. In contrast to other poly(A) RNA polymerases, lacks any RNA-binding domain. RNA-binding is mediated through its interaction with gld-3. Partially edited. RNA editing takes place in most germline-specific transcripts. Belongs to the DNA polymerase type-B-like family. GLD2 subfamily.
