CPSF2

Cleavage and polyadenylation specificity factor subunit 2 is a protein that in humans is encoded by the CPSF2 gene. This protein is a subunit of the cleavage and polyadenylation specificity factor (CPSF) complex which plays a key role in pre-mRNA 3' end processing and polyadenylation. The CPSF2 protein connects the two subunits of the complex, mCF and mPSF. Its structure contributes both to the stability of the subunits interaction and to the flexibility of the complex necessary for function. This protein has been identified as an essential subunit of the complex as certain mutations in the region inhibit CPSF complex formation.
