Western blot analysis of CSTF3 over-expressed 293 cell line, cotransfected with CSTF3 Validated Chimera RNAi ( Cat # H00001479-R01V ) (Lane 2) or non-transfected control (Lane 1). Blot probed with CSTF3 monoclonal antibody (M01), clone 1D4 (Cat # H00001479-M01 ). GAPDH ( 36.1 kDa ) used as specificity and loading control.
The protein encoded by this gene is one of three (including CSTF1 and CSTF2) cleavage stimulation factors that combine to form the cleavage stimulation factor complex (CSTF). This complex is involved in the polyadenylation and 3' end cleavage of pre-mRNAs. The encoded protein functions as a homodimer and interacts directly with both CSTF1 and CSTF2 in the CSTF complex. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq
