Cleavage stimulation factor (CstF) , a heterotrimeric protein with subunits of 77, 64, and 50 kD (CstF-77, -64, and -50), is a polyadenylation factor that helps to specify the site of processing. CstF recognizes the G+U-rich element, a sequence located downstream of the cleavage site. CstF-50 subunit interacts with the COOH-terminal domain of the RNAP II largest subunit (CTD). This subunit may be responsible for the interaction of CSTF with other factors to form a satable complex on the pre-mRNA, and multiple WD domains are required for protein interactions.
Nicotine elevates sperm motility and induces Pfn1 promoter hypomethylation in mouse testis.
p53 inhibits mRNA 3' processing through its interaction with the CstF/BARD1 complex.
The 3' ends of human pre-snRNAs are produced by RNA polymerase II CTD-dependent RNA processing.
