CSTF2

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.
Interactions.
CSTF2 has been shown to interact with CSTF3, SUB1, SYMPK, BARD1 and BRCA1.
