Biochem/physiol Actions

Cleavage and polyadenylation specificity factor subunit 1 is a protein encoded by the CPSF1 gene in humans. CPSF1 is the largest subunit of the CPSF complex composed of CPSF1, CPSF2, CPSF3, CPSF4 and FIP1L1 and is located in the nucleus. CPSF is a multi-subunit protein that plays a central role in 3′ processing of mammalian pre-mRNAs. CPF interacts directly with the AAUAAA recognition signal in the RNA and is required for the cleavage as well as for polyadenylation reaction during 3′ processing of messenger RNA precursors.
