What is Tim23 protein?

The TIM23 complex is one of the very few protein translocases in the cell capable of directing proteins across as well as into a membrane. It transports precursor proteins into two different mitochondrial subcompartments, the matrix and the inner membrane.

What does Tim44 do?

The scaffold Tim44, interacting with the matrix face of the translocon, recruits other motor subunits and binds incoming presequence. Results of in vitro experiments showed that the N-terminal domain (NTD) is intrinsically disordered and binds presequence near a region important for interaction with Hsp70 and Tim23.

Where is Tim23 located?

inner membrane
Tim23, a key component of the mitochondrial preprotein translocase, is anchored in the inner membrane by its C-terminal domain and exposes an intermediate domain in the intermembrane space that functions as a presequence receptor.

What is Tim biochemistry?

The TIM/TOM complex is a protein complex in cellular biochemistry which translocates proteins produced from nuclear DNA through the mitochondrial membrane for use in oxidative phosphorylation. The vast majority of proteins destined for the mitochondria are encoded in the nucleus and synthesized in the cytoplasm.

What is Tom biochemistry?

The translocase of the outer membrane (TOM) is a complex of proteins found in the outer mitochondrial membrane of the mitochondria. It allows movement of proteins through this barrier and into the intermembrane space of the mitochondrion.

Where are Tim and Tom located?

This protein complex is functionally analogous to the TIC/TOC complex located on the inner and outer membranes of the chloroplast, in the sense that it transports proteins into the membrane of the mitochondria. Although they both hydrolyze triphosphates, they are evolutionally unrelated.

Does calcium bind Syntaxin?

Syntaxins bind synaptotagmin in a calcium-dependent fashion and interact with voltage dependent calcium and potassium channels via the C-terminal H3 domain.
