Santos and Zasloff (1981) [PubMed 6261953] identified 12 initiator methionine tRNA genes, symbolized tRNA-i(met), in the haploid human genome. Zasloff et al. (1982) [PubMed 6923137] found a variant tRNA-i(met) with a G-to-T transversion in the highly conserved TCGA sequence in loop 4, a sequence position occupied exclusively by a purine (usually G) in almost 200 prokaryotic and eukaryotic tRNAs. One functional consequence of this base substitution is reduction in the rate of processing of the primary transcript of the gene. A second, demonstrated by microinjection into the germinal vesicle of the intact Xenopus laevis oocyte, is blockage of egress from the nucleus. It has been estimated that the human haploid genome contains 1,000 to 2,000 tRNA genes and that there are 50 to 60 chromatographically distinct tRNA species. These observations suggest redundancy of some tRNA genes. The studies of initiator methionine tRNA genes bear out this suspicion.[supplied by OMIM, Sep 2009]
