Family of short, interspersed repeats is associated with tandemly repetitive DNA in the human genome
A family of short, interspersed repeats in the human genome, designated the Mst II family, is described. The canonical structure of the repeat consists of a 220-base-pair (bp) left arm joined to a 160-bp right arm by a 39-bp junction sequence. The right arm is absent in some isolates. Some homology with the O and THE (transposon-like element) families of repeats was observed, suggesting that the Mst II elements could be a subgroup of a SINE superfamily. The 39-bp junction sequence is tandemly repeated in one of our clones. The association of tandemly repetitive sequences with Mst II elements or the putative superfamily is probably nonrandom; a search of DNA sequences data bases revealed that approximately 80 bp of the Mst II left arm occurs immediately adjacent to the tandem repeat that comprises the human homologue to the BK virus enhancer. The fortuitous occurrence of a gene duplication event involving an Mst II repeat has allowed us to estimate a mutation rate of human DNA.
