Description générale
Cytochrome c (CYCS) is mapped to human chromosome 7p15.3.[1] CYCS is a heme protein containing three long α-helices. It undergoes domain swapping at the C-terminus and exists in dimeric, trimeric, and tetrameric forms.[2] Insertion mutations in CYCS is implicated in acute myeloid leukemia.[1] Mutations in CYCS modulates the release of proplatelets and decreases platelet production leading to thrombocytopenia 4.[3]
Application
Cytochrome c from human heart has been used for the generation of standard curves in the electrochemiluminescence assay for measurement of cytochrome C levels in plasma samples[4] and in electrospray ionization mass spectrum (ESI-MS) analysis.[5]
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 c.
Actions biochimiques/physiologiques
Cytochrome c is a small heme protein that is a mobile electron carrier in the mitochondrial electron transport chain. It is also an initiator of apoptosis.
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.

Generally regarded as a universal catalyst of respiration, it forms the essential electron-bridge between the respirable substrates and oxygen.
In addition to its function in electron transport, cytochrome c acts as an apoptosis-triggering agent, forming the apoptosome with apoptosis protease-activating factor-1 (Apaf-1) and activating the caspase cascade. The two functions are finely tuned by phosphorylation of Tyr residues at position 48 and/or 97. One recent report provides suggestive evidence that phosphorylation at Tyr48 switches off the apoptotic effect.
