Protein translocation across and integration into membranes
This review details protein translocation across bacterial membranes, focusing on the signal recognition particle (SRP) and its receptor. It explores molecular mechanisms, models, and compares cotranslational with post-translational transport.
Area of Science:
- Molecular Biology
- Cell Biology
- Biochemistry
Background:
- Protein translocation is essential for cellular function.
- Understanding membrane protein integration and transport is a key area of research.
Purpose of the Study:
- To review the molecular mechanisms of protein translocation across bacterial membranes.
- To critically discuss current models and knowledge gaps in the field.
Main Methods:
- Literature review and critical analysis of existing research.

Overview of Protein Sorting and Transport
Protein sorting can be of two types: signal-based sorting and vesicle-based trafficking. In signal-based sorting, specific amino acid sequences called sorting signals target proteins to the proper location inside the cell either via gated transport or by protein translocation. In gated transport, folded...

Sec61 protein conducting channel
In eukaryotes, the translocon complex comprises a core heterotrimeric translocator channel called the Sec61 complex. This channel includes three transmembrane proteins, Sec61α, Sec61β, and Sec61γ, and is the largest subunit of the translocon complex.
