Anti-CPSF30 antibodies are used in antigen-specific immunodetection in biological samples. The target CPSF30 is a known alias name of the protein cleavage and polyadenylation specific factor 4, encoded by the CPSF4 gene in humans. This 269-amino acid residue 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. It is localized to the nucleus of the cell. The term NAR is another synonym for CPSF30. Indicated applications for CPSF30 antibodies listed below include ELISA, Western Blot, Immunofluorescence, Immunoprecipitation, and Immunohistochemistry.
