WebSRP, signal recognition particle; t and T, translocated; nt and NT, non- translocated. In this paper, we compare samples of all the different kinds of topogenic signals listed above. … Webtion process by interaction between topogenic signals within the nascent protein and response mechanisms that are, at best, only partially understood. TM proteins with single TM segments may be classified according to the initial location of their N terminus and the presence or absence of a cleaved N-terminal signal sequence.
