| Biochem/physiol Actions: | Anti-CSTF1 (C-terminal) specifically recognizes human CSTF1 (also known as Cleavage stimulation factor). |
| Biochem/physiol Actions: | Cleavage stimulation factor (50kDa) subunit is a protein encoded by the CSTF1 gene in humans. It is one of the multiple factors that plays a significant role during polyadenylation of mammalian pre-mRNAs. The mRNA polyadenylation factor CstF interacts with the BRCA1-associated protein BARD1 resulting in repression of the nuclear mRNA polyadenylation machinery. It participates in the regulation of endogenous transcripts during DNA-damage. |
| Biochem/physiol Actions: | CSTF1 is required for in vitro cleavage activity. The WD-40 repeats are crucial for the interaction with CSTF3. CSTF1 also interacts directly with the RNA polymerase II CTD, suggesting a role in linking transcription and mRNA 3′-ends processing. |

| General description: | Cleavage stimulation factor 1 (CSTF1) contains seven WD-40 repeats. The CSTF1 gene is mapped to human chromosome 20q13.2-q13.31. |
