Cleavage stimulation factor 64 kDa subunit is a protein that in humans is encoded by the CSTF2 gene.This gene encodes a nuclear protein with an RRM (RNA recognition motif) domain. The protein is a member of the cleavage stimulation factor (CSTF) complex that is involved in the 3′ end cleavage and polyadenylation of pre-mRNAs. Specifically this protein binds GU-rich elements within the 3′-untranslated region of mRNAs.
