Descripción

General description

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

Biochem/physiol Actions

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.

The ready fluctuation of cytochrome c within the cell between ferrous and ferric states, makes it an efficient biological electron-transporter. It plays a vital role in cellular oxidations in both plants and animals. Generally regarded as a universal catalyst of respiration, it forms the essential electron-bridge between the respirable substrates and oxygen.
