General description

Cytochrome C (Cyt C) is a nuclear DNA-encoded protein. It is derived from its precursor apo-cytochrome c and moves across the outer membrane of the mitochondria.

Research area: Apoptosis

Application

Se caracterizaron los sitios específicos y el grado de oxidación en el citocromo c caballo tratado con H2O2 y UV. Se sugirió que el estado de estos sitios podría utilizarse como biomarcador del entorno oxidativo de una célula.
Cytochrome c from equine heart has been used to prepare a stock solution for synthesizing and calibrating biotinylated cytochrome c. It has also been used as a component of the reaction buffer to stain electron transport chain (ETC) complex IV and determine its activity using blue-native gel electrophoresis.

Biochem/physiol Actions

El citocromo c se conoce fundamentalmente como una proteína mitocondrial transportadora de electrones. La transición del citocromo c entre los estados ferroso y férrico dentro de la célula la convierte en un eficiente transportador biológico de electrones y desempeña un papel vital en las oxidaciones celulares tanto en plantas como en animales. Se considera generalmente como un catalizador universal de la respiración, formando un puente de electrones esencial entre los sustratos respirables y el oxígeno
Cytochrome C (Cyt C) acts as a potent signaling molecule of apoptosis by activating caspase 3, a death protease. It plays a role in heme-binding with the help of cytochrome c heme lyase which facilitates its release into the mitochondrial intermembrane space. Cyt C also exhibits lipid-binding by interacting with cardiolipin, a phospholipid that initiates protein unfolding and activates the peroxidase function in Cyt C.

Interactions of cytochrome c (cyt c) with cardiolipin (CL) partially unfold the protein, activating its peroxidase function, a critical event in the execution of apoptosis. However, structural features of the altered protein species in the heterogeneous ensemble are difficult to
