Anti-CPSF7 antibodies are used in the immunodetection of the protein cleavage and polyadenylation specific factor 7. In humans, the canonical protein has a reported length of 471 amino acid residues and a mass of 52.1 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 3 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the RRM CPSF6/7 protein family, CPSF7 is a known component of the cleavage factor Im (CFIm) complex that functions as an activator of the pre-mRNA 3'-end cleavage and polyadenylation processing required for the maturation of pre-mRNA into functional mRNAs. Synonyms for this target antigen include CPSF 59 kDa subunit, cleavage and polyadenylation specificity factor 59 kDa subunit, cleavage factor Im complex 59 kDa subunit, and cleavage and polyadenylation specificity factor subunit 7. A number of CPSF7 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
