A topogenic sequence is a collective term used for a peptide sequence present at nascent proteins essential for their insertion and orienting in cellular membranes. The sequences are also used to translocate proteins across various intracellular membranes, and ensure they are transported to the correct organelle after synthesis. The position of the sequence may be at the end, e.g. N-terminal signal sequence, or in mid parts of the nascent protein, e.g. stop-transfer anchor seque… 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 …
