Description générale

Research area: Apoptosis

Cytochrome c (Cyt C) is an essential mitochondrial protein located in the inner membrane of the mitochondria. It is encoded in the nucleus as apo-cytochrome C. Cyt C occurs as membrane-bound or as soluble metalloproteins in energy-transducing membranes and is found in bacteria, archaea, and plastids. It belongs to the group of class IIa cytochromes and contains pentacoordinate heme centres.

Application

Cytochrome C from bovine heart has been used:

  • as a component of the assay solution for testing the activity of respiratory chain complexes III and IV in the mitochondria of human osteosarcoma and human hepatocarcinoma cell lines
  • to determine the cytochrome c oxidase activity in mitochondria of human aortic endothelial cells
  • as a component of the cyt C oxidase reaction solution during in situ enzyme staining of cyt C oxidase in mice kidney tissues

Actions biochimiques/physiologiques

L′interconversion rapide du cytochrome c entre les états ferreux et ferrique en font un transporteur d′électrons biologique efficace. Il joue un rôle essentiel dans les oxydations tant chez les plantes que chez les animaux. Il est généralement considéré comme un maillon essentiel de la chaîne respiratoire, car il forme un pont d′électrons essentiel entre les substrats respirables et l′oxygène.
Cytochrome C (Cyt C) is involved in the activation of caspase during the caspase-dependent apoptosis intrinsic pathway that triggers programmed cell death through apoptosis. It shows lipid-binding activity through its interaction with cardiolipin that accounts for the peroxidase activity of Cyt C. Cyt C binds to heme via the help of cytochrome c heme lyase that enables its release into the mitochondrial intermembrane space.

Notes préparatoires

Prepared with acetic acid without using TCA.

Cytochromes c are hemoproteins, with the prosthetic group covalently linked to the apoprotein, which function as electron carriers. A class of cytochromes c is defined by a CXXCH heme-binding motif where the cysteines form thioether bonds with the vinyl groups

Cytochrome c is primarily known for its function in the mitochondria as a key participant in the life-supporting function of ATP synthesis. However, when a cell receives an apoptotic stimulus, cytochrome c is released into the cytosol and triggers programmed

In healthy cells, cytochrome c (Cyt c) is located in the mitochondrial intermembrane/intercristae spaces, where it functions as an electron shuttle in the respiratory chain and interacts with cardiolipin (CL). Several proapoptotic stimuli induce the permeabilization of the outer membrane

According to dogma, initiator caspases are activated through proximity-induced homodimerization, but some studies infer that during apoptosis caspase-9 may instead form a holoenzyme with the Apaf-1 apoptosome. Using several biochemical approaches, including a novel site-specific crosslinking technique, we provide the
