TIM23 mitochondrial inner membrane pre-sequence translocase complex, motor variant Overview

GO Annotations consist of four mandatory components: a gene product, a term from one of the three Gene Ontology (GO) controlled vocabularies (Molecular Function, Biological Process, and Cellular Component), a reference, and an evidence code.


Summary
Major pre-protein translocase in the inner membrane of mitochondria, mediates the translocation of N-terminal, positively charged pre-sequence-containing proteins. TIM50 interacts with incoming pre-sequence-carrying pre-proteins as they reach the trans site of the TOM40 complex (CPX-474). Pre-proteins are directed by the intermembrane space-exposed domains of TIM50, and TIM23 to the protein-conducting channel of the TIM23 complex. The pre-sequence translocase-associated motor (PAM) drives the completion of pre-protein translocation into the matrix. In most cases, the pre-sequence is proteolytically removed by the mitochondrial-processing peptidase (CPX-1630).
GO Slim Terms

The yeast GO Slim terms are higher level terms that best represent the major S. cerevisiae biological processes, functions, and cellular components. The GO Slim terms listed here are the broader parent terms for the specific terms to which this gene product is annotated, and thus represent the more general processes, functions, and components in which it is involved.
