Protein Classification

LYR motif-containing protein( domain architecture ID 1563021)

LYR motif-containing protein may play a key role in the assembly and function of complexes I, II, and III; LYR motifs are molecular signatures of specific recipient Fe-S proteins or accessory factors that assist Fe-S cluster delivery; similar to Caenorhabditis elegans protein FMC1 homolog

 26-83 2.62e-22

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.

 26-83 2.62e-22

LYR (leucine-tyrosine-arginine) motif found in formation of mitochondrial complex V assembly factor 1 (FMC1) and similar proteins; FMC1, also known as formation of mitochondrial complexes protein 1, is an ATP synthase assembly factor that plays a role in the assembly/stability of the mitochondrial membrane ATP synthase (F(1)F(0) ATP synthase or Complex V). It 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.
