Summary Human Mitochondrial Translation Initiation Factor 2 (MTIF2) is a nuclear gene. Its product, IF2mt, is needed for the process of translation in mitochondria. IF2 is made on cytoplasmic ribosomes in the cytosol, and then imported into the mitochondrial matrix. It catalyzes the binding of IMet-tRNA to the ribosomal small subunit. Complete cDNAs encoding human IF2mt have been isolated from cDNA libraries, cloned and sequenced. (Ma and Spremulli, 1995). Several genomic clones containing MTIF2 have been isolated from a Lambda Fix" library and the DNA sequenced. The chromosomal location of the gene was found using a somatic cell hybrid panel. Each DNA sample contained mouse chromosomes and one intact human chromosome. The polymerase chain reaction (PCR) technique, using two PCR primers designed from MTIF2 sequence data showed the location of the gene to be on chromosome 2. The PCR primers anneal to DNA sequences flanking the intron/exon junction near the 3'-end of the gene. Human parental DNA served as a positive control and mouse genomic DNA as a negative control. The fluorescence in situ hybridization (FISH) technique confirmed the location. Four human genomic clones containing overlapping fragments were used as probes on human metaphase chromosome spreads. A more precise location of the gene was achieved by G-banding of the metaphase spreads used in FISH. MTIF2 was mapped to the short arm of chromosome 2 in the region 2pl6 to 2pl4 (Bonner et al., 1998).
