Cofactor	Binds 2 magnesium ions. Also active with manganese. Ref.13
Subunit structure	Component of the cleavage and polyadenylation factor (CPF) complex, which is composed of PTI1, SYC1, SSU72, GLC7, MPE1, REF2, PFS2, PTA1, YSH1/BRR5, SWD2, CFT2/YDH1, YTH1, CFT1/YHH1, FIP1 and PAP1. Interacts with FIR1 and RRP6. Ref.5 Ref.6 Ref.14
Subcellular location	Nucleus Ref.7 Ref.8.
Miscellaneous	Present with 17100 molecules/cell in log phase SD medium. Ref.9
Sequence similarities	Belongs to the poly(A) polymerase family.
