General description
Cytochrome C is a heme protein. It is localized between the inner and outer mitochondrial membranes.
Application
Cytochrome c from bovine heart has been used:
- for cytochrome oxidase staining using the mice brain tissue
- as a component of control mixture to evaluate the accuracy of tandem mass spectra in identifying peptides
- to study its effect on the stability, transport, and retention of biochar colloids (BCs) in saturated porous media under various solution pH and ionic strength (IS) conditions
- as a component of staining solution for the detection of cytochrome oxidase activity in the brain tissue sections of mouse
- as a component in the assay to study its superoxide scavenging efficiency
- as a component of serum-free DMEM media to evaluate non-specific cytochrome C reduction in astrocytes and HT-29 cells
Biochem/physiol Actions
Cytochrome C is a key mediator of oxidative phosphorylation. It mediates the electron transport between complex III and complex IV of the respiratory chain.
Cytochrome c has been identified as an important mediator in apoptotic pathways. The release of mitochondrial cytochrome c into the cytoplasm stimulates apoptosis and is commonly used as an indicator of the apoptotic process in the cell. Investigation on the effect of Paris Saponin I (PS I) on human gastric carcinoma cell growth (SGC7901 cells) have shown an elevated level cytoplasmic cytochrome c. Results are an inhibition of proliferation in SGC7901 cells by inducing mitochondria-dependent apoptosis through cytochrome.
The ready interconversion of cytochrome c between ferrous and ferric states makes it an efficient biological electron carrier. It plays a vital role in cellular oxidations in both plants and animals. Generally regarded as a universal link in the respiratory chain, it forms the essential electron-bridge between the respirable substrates and oxygen.
