RG   NIH - Xenopus Gene Collection (XGC) project;
RL   Submitted (AUG-2004) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: Component of the cleavage and polyadenylation specificity
CC       factor (CPSF) complex that play a key role in pre-mRNA 3'-end
CC       formation, recognizing the AAUAAA signal sequence and interacting with
CC       poly(A) polymerase and other factors to bring about cleavage and
CC       poly(A) addition. Cpsf4 binds RNA polymers with a preference for
CC       poly(U) (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Component of the cleavage and polyadenylation specificity
CC       factor (CPSF) complex, composed of cpsf1, cpsf2, cpsf3, cpsf4 and
CC       fip1l1. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the CPSF4/YTH1 family. {ECO:0000305}.
