UQCRC1 physically associates with cytochrome c (cyt-c), and UQCRC1 deficiency increases cytochrome c in the cytoplasmic fraction and activates the caspase cascade, leading to neuronal apoptosis; depleting cyt-c or expressing anti-apoptotic p35 ameliorates UQCRC1-deficiency-mediated neurodegeneration. |

UQCRC1 overexpression in pancreatic cancer cells increases mitochondrial oxidative phosphorylation (OXPHOS) and ATP production; the overproduced ATP is released extracellularly via the pannexin 1 channel and acts as an autocrine/paracrine agent to promote cell proliferation through the ATP/P2Y2-RTK/AKT signaling axis. |

Neuronal knockdown of uqcrc1 in Drosophila causes age-dependent dopaminergic neuron reduction and locomotor decline; lethality of uqcrc1-KO is rescued by neuronal UQCRC1 expression but not by the disease-causing variant (p.Tyr314Ser), establishing the variant as loss-of-function pathogenic. |

Oxidation of Trp395 in UQCRC1 (identified in a cardiotoxin myodegeneration model) causes large structural changes in mitochondrial complex III; molecular dynamics simulation shows decreased plasticity of the complex due to cross-talk among matrix-facing and intermembrane space subunits, impairing electron flow from cytochrome c. |

FGF21 inhibits oxLDL-induced HUVEC pyroptosis through a TET2-UQCRC1-ROS pathway: FGF21 upregulates TET2, which upregulates UQCRC1 expression; UQCRC1 silencing aggravates pyroptosis and impairs mitochondrial function and increases ROS production. |

UQCRC1 overexpression in pancreatic cancer cells inhibits NK cell cytotoxicity and chemotaxis via elevated extracellular ATP and its metabolite adenosine acting through P2Y11R and A2AR receptors; mechanistically, the UQCRC1/eATP axis reduces CCL5 chemokine expression in cancer cells and shifts the balance of activating receptor DNAM-1 vs. inhibitory receptor CD96 on NK cells toward exhaustion. |
