Background
The cleavage stimulation factor complex (CSTF) is composed of three subunits: CSTF1, CSTF2, and CSTF3. CSTF binds and recruits the cleavage and polyadenylation specificity factor complex to regulate 3’-untranslated regions (3'-UTRs) of pre-mRNAs (1,2). Within CSTF, CSTF3 forms a bridge that binds to CSTF1 and CSTF2. CSTF2, also known as CSTF64, binds directly to mRNA through G/U- or U-rich sequences via its N-terminal RNA recognition motif (1,2). CSTF1 is capable of binding to the C-terminal domain (CTD) of RNA Pol II, coupling mRNA processing with transcription (3). Additionally, CSTF1 can also bind to BRCA1-associated protein BARD1, which inhibits the polyadenylation machinery during DNA damage and tumor suppression (4,5).
CSTF2, through its ability to directly bind RNA, has been implicated in many cellular functions and diseases. In embryonic stem cells, CSTF2 controls pluripotency and cell cycle through 3’-end processing of histone mRNAs (6). Widespread shortening of 3’-UTRs has been a phenomenon described in many cancer types. Overexpression of CSTF2 shortens the poly(A) tails of oncogenes, resulting in evasion of miRNA repression and transformation (7).
