WebJul 29, 2009 · CIS-REGULATION OF GENE EXPRESSION. The transcription of RNA polymerase II (Pol II)-dependent genes is mediated by the recruitment of general and sequence-specific transcription factors to cis-acting regulatory sequences including core and proximal promoter elements that reside within 1 kb of the transcription start site … WebAug 1, 2024 · The sizes of cis-regulatory effects on expression variation were 1.98 and 1.88 times larger than trans-regulatory effects in heads and bodies, respectively. A generalized linear model analysis revealed that both cis- and trans-regulated expression variation was strongly associated with nonsynonymous nucleotide diversity and tissue specificity.

WebThough certain cis-acting elements can effectively prevent the methylation of DNA, other sequences can enhance DNA methylation. For example, Mummanemi et al. ( 96 ) showed conclusively that a cis-acting element located 1.3 kb upstream of the mouse aprt gene acted as a signal for the methylation and epigenetic inactivation of the gene.
