MTFMT

The protein encoded by this nuclear gene localizes to the mitochondrion, where it catalyzes the formylation of methionyl-tRNA.

Full Name

MITOCHONDRIAL METHIONYL-TRNA FORMYLTRANSFERASE

Function

Methionyl-tRNA formyltransferase that formylates methionyl-tRNA in mitochondria and is crucial for translation initiation.

Biological Process

Conversion of methionyl-tRNA to N-formyl-methionyl-tRNA Source: UniProtKB

Cellular Location

Mitochondrion

Involvement in disease

Combined oxidative phosphorylation deficiency 15 (COXPD15):
An autosomal recessive, mitochondrial, neurologic disorder characterized by features of Leigh syndrome and combined oxidative phosphorylation deficiency. Clinical features include mild global developmental delay, white matter abnormalities, ataxia, incoordination, speech and reading difficulties, T2-weighted hyperintensities in the basal ganglia, corpus callosum, and brainstem.
Mitochondrial complex I deficiency, nuclear type 27 (MC1DN27):
A form of mitochondrial complex I deficiency, the most common biochemical signature of mitochondrial disorders, a group of highly heterogeneous conditions characterized by defective oxidative phosphorylation, which collectively affects 1 in 5-10000 live births. Clinical disorders have variable severity, ranging from lethal neonatal disease to adult-onset neurodegenerative disorders. Phenotypes include macrocephaly with progressive leukodystrophy, non-specific encephalopathy, cardiomyopathy, myopathy, liver disease, Leigh syndrome, Leber hereditary optic neuropathy, and some forms of Parkinson disease. MC1DN27 transmission pattern is consistent with autosomal recessive inheritance.
