WebA topologically associating domain (TAD) is a self-interacting genomic region, meaning that DNA sequences within a TAD physically interact with each other more frequently than with sequences outside the TAD. [1] The median size of a TAD in mouse cells is 880 kb, and they have similar sizes in non-mammalian species.

WebMay play a role in preventing the propagation of stable methylation at the escape genes from X- inactivation. Involved in sister chromatid cohesion. Associates with both centromeres and chromosomal arms during metaphase and required for cohesin localization to CTCF sites. Regulates asynchronous replication of IGF2/H19. WebAug 27, 2009 · Insulator elements mediate intra- and inter-chromosomal interactions. The insulator protein CCCTC-binding factor (CTCF) is important for insulator function in several animals but a report in BMC Molecular Biology shows that Caenorhabditis elegans, yeast and plants lack CTCF. Alternative proteins may have a similar function in these organisms.
WebMar 25, 2011 · Due to their inherently hypoxic environment, cancer cells often resort to glycolysis, or the anaerobic breakdown of glucose to form ATP to provide for their energy needs, known as the Warburg effect.
