These Cleavage and Polyadenylation Specific Factor 1, 160kDa ELISA kits are immunodetection tools for measuring specific protein levels in biological samples. Cleavage and Polyadenylation Specific Factor 1, 160kDa is an alias of the human CPSF1 gene, which encodes the protein, cleavage and polyadenylation specific factor 1. The protein is a known component of the cleavage and polyadenylation specificity factor (CPSF) complex that plays 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. The CPSF1 protein is described to be 1443 amino acid residues in length and 160.9 kilodaltons in mass. It is localized to the nucleus of the cell. In terms of tissue specificity, it is found to be widely expressed, with high expression in the retina. Other names for this target antigen include CPSF160, HSU37012, and MYP27.
