Pre-mRNA splicing is a complex process involving combinatorial effects of cis- and trans-elements. Here, we focused on histone modifications as typical trans-regulatory elements and performed systematic analyses of associations between splicing patterns and histone modifications by using publicly available ChIP-Seq, mRNA-Seq, and exon-array data obtained in two human cell lines. We found that several...
The Chi sequences are specific oligomers that stimulate DNA repair by homologous recombination, and are different sequences in each organism. Approximately 75% of the copies of the Chi sequence (5'-GCTGGTGG-3') of Escherichia coli reside on the leading strand, and this orientation bias is often believed to be a consequence of the biological role of Chi sequences as the signal sequence of RecBCD pathway...
