Protein attributes
| Sequence length | 717 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is further processed into a mature form. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Involved in the 5-carboxymethylaminomethyl modification (mnm5s2U34) of the wobble uridine base in mitochondrial tRNAs. Ref.1 |
| Cofactor | FAD By similarity. |
| Subcellular location | Mitochondrion By similarity. |
| Tissue specificity | Ubiquitously expressed in various tissues, but with a markedly elevated expression in tissues of high metabolic rates including cochlea. Ref.1 |
| Involvement in disease | Combined oxidative phosphorylation deficiency 10 (COXPD10) [MIM:614702]: An autosomal recessive disorder resulting in variable defects of mitochondrial oxidative respiration. Affected individuals present in infancy with hypertrophic cardiomyopathy and lactic acidosis. The severity is variable, but can be fatal in the most severe cases. |
| Sequence similarities | Belongs to the MnmG family. |
| Sequence caution | The sequence AAD27712.1 differs from that shown. Reason: Frameshift at position 9. The sequence AAH05808.2 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened. |
