title: Definition, distribution, and use of a conserved Bovidae retroposon element sequence motif.
abstract: Based on a data-base search, the sequences of 32 Bovidae retroposon elements have been compared. Two conserved areas are identified, and one of the corresponding sequences of the derived bovine consensus was used to design oligonucleotides as primer molecules for random DNA amplification of Bovidae DNA. Such a primer binding site should occur on average every 10,000 bp in the bovine genome, as suggested by a survey of published sequences. This estimate about the distribution of these possible primer binding sites was experimentally substantiated by mapping four of these primer binding sites within 40 kb of contiguous bovine DNA, carrying the heretofore undescribed bovine lactoferrin gene. Furthermore, these conserved, ubiquitous sequence motifs prove to be useful for mapping of bovine DNA.
