Supplementary information

UQCRFS1 also known as RISP functions as an essential component of the mitochondrial electron transport chain. The protein weighs approximately 29 kDa and plays an important role in the transfer of electrons from ubiquinol to cytochrome c within complex III also named cytochrome bc1 complex. UQCRFS1 expresses primarily in tissues with high energy requirements such as heart and skeletal muscle due to their reliance on aerobic metabolism for ATP production.

Biological function summary

RISP belongs to the cytochrome bc1 complex a large multimeric structure involved in mitochondrial respiratory function. By facilitating electron transfer it contributes to the establishment of the proton gradient across the inner mitochondrial membrane. This gradient drives ATP synthesis through oxidative phosphorylation highlighting its importance for cellular energy homeostasis. The reduction and oxidation of ubiquinone and cytochrome c ensure effective electron flow within this system.

Pathways

RISP integrates into essential processes within the respiratory chain and oxidative phosphorylation pathways. It directly interacts with other proteins in complex III such as UQCRH and UQCRC1 to facilitate protein complex stability and function. Additionally RISP supports the interaction between complex III and complex IV by aiding in the electron transfer ensuring efficient ATP production. This association clarifies the interprotein dynamics needed for proper mitochondrial respiratory operation.

RISP connects to mitochondrial dysfunction and related pathologies. Mitochondrial complex III deficiencies often link to neurodegenerative disorders like Leigh syndrome due to defective oxidative phosphorylation. Such deficiencies may result from perturbations in RISP function or expression affecting electron transport chain efficiency. Furthermore disruptions in RISP activity relate to ischemic conditions where hypoxic stress compromises ATP production implicating it together with cytochrome c in cellular energy crises.

Target data

Cytochrome b-c1 complex subunit Rieske, mitochondrial. Component of the ubiquinol-cytochrome c oxidoreductase, a multisubunit transmembrane complex that is part of the mitochondrial electron transport chain which drives oxidative phosphorylation (PubMed : 31883641). The respiratory chain contains 3 multisubunit complexes succinate dehydrogenase (complex II, CII), ubiquinol-cytochrome c oxidoreductase (cytochrome b-c1 complex, complex III, CIII) and cytochrome c oxidase (complex IV, CIV), that cooperate to transfer electrons derived from NADH and succinate to molecular oxygen, creating an electrochemical gradient over the inner membrane that drives transmembrane transport and the ATP synthase. The cytochrome b-c1 complex catalyzes electron transfer from ubiquinol to cytochrome c, linking this redox reaction to translocation of protons across the mitochondrial inner membrane, with protons being carried across the membrane as hydrogens on the quinol. In the process called Q cycle, 2 protons are consumed from the matrix, 4 protons are released into the intermembrane space and 2 electrons are passed to cytochrome c. The Rieske protein is a catalytic core subunit containing a [2Fe-2S] iron-sulfur cluster. It cycles between 2 conformational states during catalysis to transfer electrons from the quinol bound in the Q(0) site in cytochrome b to cytochrome c1 (By similarity). Incorporation of UQCRFS1 is the penultimate step in complex III assembly (PubMed : 28673544).. Cytochrome b-c1 complex subunit 9. Component of the ubiquinol-cytochrome c oxidoreductase (cytochrome b-c1 complex, complex III, CIII). UQCRFS1 undergoes proteolytic processing once it is incorporated in the complex III dimer. One of the fragments, called subunit 9, corresponds to its mitochondrial targeting sequence (MTS). The proteolytic processing is necessary for the correct insertion of UQCRFS1 in the complex III dimer, but the persistence of UQCRFS1-derived fragments may prevent newly imported UQCRFS1 to be processed and assembled into complex III and is detrimental for the complex III structure and function.
