Topogenic signals
WebThe generalization of the Signal Hypothesis to include signals for every organelle and location within the cell had an impact far beyond illuminating the targeting of secretory proteins, as it introduced the concept of 'topogenic' signals for the first time. WebJul 1, 2024 · Despite identification of several topogenic signals in polytopic membrane proteins [15], the cellular mechanisms involved in responding to these signals are not fully understood. Experiments with 4-TMD EmrE demonstrated that a single positively charged residue can exert its toplogical effects globally [29].

WebOct 12, 1999 · The targeting signal is conserved among all known heme lyases and represents a general topogenic signal for protein sorting to the intermembrane space. The chemical properties of the “heme lyase targeting signal” are distinct from those of presequences. Therefore, this sequence represents a distinct targeting signal that …
WebThe topogenic signal is suggested to comprise a Ser-Lys-Leu (SKL)-containing sequence located at the extreme carboxyl terminus (for a review, see Osumi and F’ujiki (1990)).
