Mitochondrial methionyl-tRNA formyltransferase is a protein that in humans is encoded by the MTFMT gene.[3]

The protein encoded by this nuclear gene localizes to the mitochondrion, where it catalyzes the formylation of methionyl-tRNA.[3] Recessive-type mutations in MTFMT have been shown to cause mitochondrial disease [4]

Model organisms[edit]

Model organisms have been used in the study of MTFMT function. A conditional knockout mouse line, called Mtfmttm1a(KOMP)Wtsi[9][10] was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists — at the Wellcome Trust Sanger Institute.[11][12][13]

Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.[7][14] Twenty six tests were carried out on mutant mice and two significant abnormalities were observed.[7] During gestation homozygous mutant embryos displayed lethal growth retardation and oedema. In a separate study, no homozygous animals were observed at weaning. The remaining tests were carried out on adult heterozygous mutant animals, but no further abnormalities were seen.[7]
