Poly(A) RNA polymerase GLD2 (Tent2)

Cytoplasmic poly(A) RNA polymerase that adds successive AMP monomers into the 3'-end of specific RNAs, forming a poly(A) tail. Compared to the canonical nuclear poly(A) RNA polymerase, it only adds poly(A) to selected cytoplasmic mRNAs.

Does not play a role in replication-dependent histone mRNA degradation (By similarity). .
