Cleavage Stimulation Factor
MESHD039241
A RNA-binding protein that stimulates the cleavage of the 3' end of MRNA near the POLYADENYLATION site. It is a heterotrimer of 55-, 64- and 77-kDa subunits and combines with CLEAVAGE STIMULATION FACTOR to form a stable complex with mRNA that directs the 3' cleavage and polyadenylation reaction.
