    basic FUNCTION
  • function as an iron-sulfur protein binding factor
  • appears to be involved in development of more aggressive phenotype of breast cancer
  • may be likely part of mitochondrial permeability transition(MPT) pores and dephosphorylation of UQCRFS1 may play a role in regulation of the MPT
  • is essential for Complex III (CIII) activity
  • UQCRFS1 is the last incorporated mitochondrial complex III (cIII) subunit, and its presence is essential for enzymatic activity
  • crucial role of UQCRFS1 for the catalytic function of CIII
    • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
    a component
  • component of the ubiquinol-cytochrome C reductase complex (complex III or cytochrome b-c1 complex), which is part of the mitochondrial respiratory chain
    • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • works as a human Rieske Fe-S protein (UQCRFS1) chaperone, binding to this subunit within the mitochondrial matrix and stabilizing it prior to its translocation and insertion into the late CIII dimeric intermediate within the mitochondrial inner membrane
  • HSCB, essential for Fe-S cluster biogenesis of SDHB, directly binds LYRM7, formerly described as a chaperone that stabilizes UQCRFS1 prior to its insertion into CIII
