The cleavage and polyadenylation specific factor 2, 100kDa ELISA kits listed below are analytical tools for measuring concentrations of cleavage and polyadenylation specific factor 2, 100kDa in various samples. cleavage and polyadenylation specific factor 2, 100kDa is an alternative name for the human CPSF2 gene, which encodes the protein, cleavage and polyadenylation specific factor 2. The target protein is a known component of the cleavage and polyadenylation specificity factor (CPSF) complex that play a key role in pre-mRNA 3'-end formation, recognizing the AAUAAA signal sequence and interacting with poly(A) polymerase and other factors to bring about cleavage and poly(A) addition. Structurally, the CPSF2 protein is described to be 782 amino acid residues in length and 88.5 kilodaltons in mass. It is localized to the nucleus of the cell. Other names for this target antigen include CPSF100, CPSF100, and cleavage, and polyadenylation specificity factor subunit 2.
