Background Information

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 unit interacts with the COOH-terminal domain of the RNAP II largest subunit (CTD).
