title: Nucleotide sequence analysis of cellular flanking regions of intracisternal A-particle gene 81.
abstract: The cellular nucleotide sequences flanking the mouse intracisternal A-particle gene 81 were determined. The results indicated that they were made of many small oligonucleotide repeats both direct and indirect in orientation. These two different kinds of repeating sequences were often found to be overlap. The overall base composition of this region is relatively A + T rich. The most important feature of the sequences determined was that it consists of several repeated dinucleotide tracts containing a (CA)16 repeating cluster in the 5' end flanking region of one strand and another repeating dinucleotide cluster, (GT)16, in the 3' end flanking region of the same strand of this gene. In addition, the existence of two clusters of 9 continuous 5-bp repeat units, GCTTT, was found in the 3' end flanking region. The possible roles of such repeating sequence were discussed.
