“…This finding broadens our knowledge of CR1 distribution. In addition to propagating in a reverse trasncriptase dependent manner and dispersing randomly flanking multiple genes (Reitman et al 1993;Stumph et al 1981;Stumph et al 1983), the CR1 elements may also accumulate within satellite regions owing to the amplification of HinfI monomer units.…”

Highly repetitive DNA sequences constitute a significant portion of most eukaryotic genomes, raising questions about their evolutionary origins and amplification dynamics. In this study, a novel chicken repetitive DNA family, the HinfI repeat, was characterized. The basic repeating unit of this family displays a uniform length of 770 bp, which was defined by the recognition site of HinfI. The HinfI repeat was specifically localized in the pericentric region of chromosome 4 by fluorescence in situ hybridization and constitutes 0.51% of the chicken genome. Interestingly, a chicken repeat 1 (CR1) element has been identified within this basic repeating unit. Like other CR1 elements, this CR1 element also displays typical retrotransposition characteristics, including a highly conserved 3' region and a badly truncated 5' end. This direct evidence from sequence analysis, together with our Southern blot results, suggests that the HinfI repeat may originate from a unique region containing a retrotransposed CR1 element.

“…A cluster of CR1 repeats constitutes almost 16% of the chicken β-globin gene cluster (Reitman et al 1993). Over 19 CR1 elements have been found to flank both the upstream and downstream regions of the chicken ovalbumin gene (Stumph et al 1983). However, no CR1 element was reported to be located within the satellite region.…”

Current attention in transcriptional regulation is focused on the properties of coactivators and corepressors that mediate communication between sequence-specific transcription factors, the basal transcriptional machinery and the chromatin environment. Nuclear and steroid hormone receptors represent the best-understood transcription factors that utilize coactivators and corepressors. This review considers the access of these receptors to chromatin, the modifications of chromatin structure that the receptors instigate and the implications for transcriptional control. Nucleosome positioning and targeted histone modification emerge as central controlling elements for gene expression.
