The human genome has at least ten LYR proteins that were predominantly identified as mitochondrial proteins. Some family members were also found in the cytosol or nucleus. LYR motif-containing protein 4 (LYRM4) represents the only LYR protein that is directly involved in the first steps of Fe-S cluster generation. Other LYR proteins have been identified as accessory subunits or assembly factors of mitochondrial OXPHOS (oxidative phosphorylation) complexes I, II, III and V, and they play specific roles in acetate metabolism.

LYR (leucine-tyrosine-arginine) motif found in mitochondrial succinate dehydrogenase assembly factor 3 (SDHAF3) and similar proteins; SDHAF3, also called SDH assembly factor 3, or LYR motif-containing protein 10 (LYRM10), plays an essential role in the assembly of succinate dehydrogenase (SDH), an enzyme complex (also referred to as respiratory complex II) that is a component of both the tricarboxylic acid (TCA) cycle and the mitochondrial electron transport chain, and which couples the oxidation of succinate to fumarate with the reduction of ubiquinone (coenzyme Q) to ubiquinol. It promotes maturation of the iron-sulfur protein subunit SDHB of the SDH catalytic dimer, protecting it from the deleterious effects of oxidants. SDHAF3 may act together with SDHAF1. Its mutations may be associated with idiopathic SDH-associated diseases. SDHAF3 belongs to the Complex1_LYR-like superfamily that consists of proteins of diverse functions that are exclusively found in eukaryotes and contain the conserved tripeptide 'LYR' close to the N-terminus.

LYR (leucine-tyrosine-arginine) motif found in LYR motif-containing protein 7 (LYRM7) and similar proteins; LYRM7 is an assembly factor required for Rieske iron sulfur (Fe-S) protein UQCRFS1 incorporation into the cytochrome b-c1 (CIII) complex. It functions as a 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. LYRM7 mutations cause a multifocal cavitating leukoencephalopathy with a distinct and recognizable magnetic resonance imaging (MRI) pattern. LYRM7 belongs to the Complex1_LYR-like superfamily that consists of proteins of diverse functions that are exclusively found in eukaryotes and contain the conserved tripeptide 'LYR' close to the N-terminus.
