Cleavage and polyadenylation specificity factor subunit 3 is a protein that in humans is encoded by the CPSF3 gene. Model organisms Model organisms have been used in the study of CPSF3 function. A conditional knockout mouse line called Cpsf3tm1b(EUCOMM)Wtsi was generated at the Wellcome Trust Sanger Institute. Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion. Additional screens performed: - In-depth immunological phenotyping References External links Further reading
