Cstf and cpsf
WebHowever, as discussed above, our data rule out models in which the trigger to terminate is delivered during a zero order CPSF-CstF capture event, because an antisense to the poly(A) signal, placed far downstream, aborts the first order termination process (Fig. 4D, solid line). Thus, we are driven to the view that the final triggering event ...
