WebSep 24, 2024 · The enzyme CPSF is responsible for the cleavage, which occurs 10–30 nucleotides downstream of its binding site. This location typically contains the polyadenylation signal sequence AAUAAA on the RNA, however variations exist that bind CPSF less strongly. Two more proteins, CstF and CFI, give specificity to the RNA … WebJun 17, 2007 · CPSF can also bind CstF, but this seems to be mutually exclusive with polymerase binding. We suggest that CPSF, while binding the body of the polymerase, scans for hexamers in the extruding RNA ...
