LYR (leucine-tyrosine-arginine) motif found in NADH dehydrogenase [ubiquinone] 1 beta subcomplex subunit 9 (NDUFB9) and similar proteins; NDUFB9, also called LYR motif-containing protein 3 (LYRM3), or Complex I-B22 (CI-B22), or NADH-ubiquinone oxidoreductase B22 subunit (UQOR22), is an accessory subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (complex I), and is believed to be not involved in catalysis. In general, accessory subunits are integral for assembly and function of Complex I, which functions in the transfer of electrons from NADH to the respiratory chain. NDUFB9 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 Complex1_LYR-like superfamily; The Complex1_LYR-like superfamily consists of proteins of diverse functions that are exclusively found in eukaryotes and contain the conserved tripeptide 'LYR' close to the N-terminus. 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.

 16-69 6.01e-05

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.

LYR (leucine-tyrosine-arginine) motif found in LYR motif-containing protein 1 (LYRM1) and similar proteins; LYR motif-containing protein 1 (LYRM1) may promote cell proliferation and inhibition of apoptosis of preadipocytes. Overexpression of the human LYRM1 causes mitochondrial dysfunction and induces insulin resistance in 3T3-L1 adipocytes. LYRM1 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 4 (LYRM4) and similar proteins; LYRM4, also called ISD11, is a eukaryote-specific component of the mitochondrial biogenesis of Fe-S clusters which are essential cofactors in multiple processes, including oxidative phosphorylation. It is required for nuclear and mitochondrial iron-sulfur protein biosynthesis by forming a complex with, and stabilizing, the sulfur donor NFS1. LYRM4 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.
