A membrane-bound flavoenzyme complex consisting of four subunits, A, B, C, and D. A and B comprise the membrane-extrinsic catalytic domain and C (InterPro:IPR003510; InterPro:IPR004224) and D (InterPro:IPR003418) link the catalytic centers to the electron-transport chain. This family consists of the 13 kDa hydrophobic subunit D. This component may be required to anchor the catalytic components of the fumarate reductase complex to the cytoplasmic membrane. Fumarate reductase couples the reduction of fumarate to succinate to the oxidation of quinol to quinone, in a reaction opposite to that catalyzed by the related complex II of the respiratory chain (succinate dehydrogenase-(ubiquinone)).

A membrane-bound flavoenzyme complex consisting of four subunits, A, B, C, and D. A and B comprise the membrane-extrinsic catalytic domain and C (InterPro:IPR003510; InterPro:IPR00224) and D (InterPro:IPR003418) link the catalytic centers to the electron-transport chain. In some species, the complex has only three subunits, and in these cases, there is only one membrane anchor instead of two. This family consists of the 13 kDa hydrophobic subunit D. This component may be required to anchor the catalytic components of the fumarate reductase complex to the cytoplasmic membrane. Fumarate reductase couples the reduction of fumarate to succinate to the oxidation of quinol to quinone, in a reaction opposite to that catalyzed by the related complex II of the respiratory chain (succinate dehydrogenase-(ubiquinone)). Examples of this component are found in bacterial species.

Any process that stops, prevents, or reduces the frequency, rate or extent of activated T cell autonomous cell death.

Any process that modulates the occurrence or rate of activated T cell autonomous cell death.

Any process that activates or increases the frequency, rate or extent of activated T cell autonomous cell death.

A protein complex that transfers electrons from ubiquinol to cytochrome c and translocates two protons across a membrane. The complex contains a core structure of three catalytic subunits: cytochrome b, the Rieske iron sulfur protein (ISP), and cytochrome c1, which are arranged in an integral membrane-bound dimeric complex; additional subunits are present, and vary among different species.

Any apoptotic process in a thymocyte, an immature T cell located in the thymus.

A part of the respiratory chain located in the plasma membrane, containing about 10 polypeptide subunits including four redox centers: cytochrome b/b6, cytochrome c1 and an 2Fe-2S cluster. Catalyzes the oxidation of ubiquinol by oxidized cytochrome c1. Examples of this component are found in bacterial species.

Any process that modulates the occurrence or rate of thymocyte death by apoptotic process.

A part of the respiratory chain, containing the 13 polypeptide subunits of cytochrome c oxidase, including cytochrome a and cytochrome a3. Catalyzes the oxidation of reduced cytochrome c by dioxygen (O2).

Any process that stops, prevents, or reduces the frequency, rate or extent of thymocyte death by apoptotic process.

A part of the respiratory chain located in the plasma membrane, containing the 13 polypeptide subunits of cytochrome c oxidase, including cytochrome a and cytochrome a3. Catalyzes the oxidation of reduced cytochrome c by dioxygen (O2). Examples of this component are found in bacterial species.

Any process that activates or increases the frequency, rate or extent of thymocyte death by apoptotic process.

Any apoptotic process in a natural killer cell, a lymphocyte that can spontaneously kill a variety of target cells without prior antigenic activation.

Any apoptotic process in a lymphocyte, a leukocyte commonly found in the blood and lymph that has the characteristics of a large nucleus, a neutral staining cytoplasm, and prominent heterochromatin.

Any process that modulates the occurrence or rate of natural killer cell death by apoptotic process.

Any process that modulates the occurrence or rate of lymphocyte death by apoptotic process.

Any process that stops, prevents, or reduces the frequency, rate or extent of natural killer cell death by apoptotic process.
