General description

Research area: Apoptosis

Cytochrome c (Cyt C) is an essential mitochondrial protein located in the inner membrane of the mitochondria.[1] It is encoded in the nucleus as apo-cytochrome C.[2] Cyt C occurs as membrane-bound or as soluble metalloproteins in energy-transducing membranes and is found in bacteria, archaea, and plastids.[1] It belongs to the group of class IIa cytochromes and contains pentacoordinate heme centres.[3]

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[4]
to determine the cytochrome c oxidase activity in mitochondria of human aortic endothelial cells[5]
as a component of the cyt C oxidase reaction solution during in situ enzyme staining of cyt C oxidase in mice kidney tissues[6]

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.[7] It shows lipid-binding activity through its interaction with cardiolipin that accounts for the peroxidase activity of Cyt C.[1] Cyt C binds to heme via the help of cytochrome c heme lyase that enables its release into the mitochondrial intermembrane space.[8]

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.
