The TIM23 complex imports proteins into mitochondria. This review covers recent findings on its structure and function as a key molecular machine.
Area of Science:
- Mitochondrial biology
- Protein import machinery
Background:
- The TIM23 complex is crucial for protein translocation across the mitochondrial inner membrane.
- It mediates the import of numerous mitochondrial proteins, including those destined for the matrix and inner membrane.
Purpose of the Study:
- To provide an overview of recent advancements in understanding the TIM23 complex.
- To highlight current insights into the structure and function of this protein import machinery.
Main Methods:
- Literature review of recent structural and functional studies.
- Analysis of current research on the TIM23 complex.
Main Results:
- The TIM23 complex is a sophisticated machine with dynamic structural features.
- Recent studies have elucidated key functional mechanisms of protein translocation mediated by TIM23.
Conclusions:
- The TIM23 complex plays a vital role in mitochondrial protein homeostasis.
- Continued research is essential for a comprehensive understanding of its structure-function relationship and implications in health and disease.

Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...
