Cleavage and Polyadenylation Specificity Factor Subunit 5

**Semantic type:** Amino Acid, Peptide, or Protein

**Definition:** Cleavage and polyadenylation specificity factor subunit 5 (227 aa, ~26 kDa) is encoded by the human NUDT21 gene. This protein is involved in the recruitment of multiprotein complexes to the cleavage and polyadenylation signals (pA signals) on the 3'-end of pre-mRNA.
