WebNov 17, 2016 · The anchor sites of CTCF contact domains are bound by CTCF and cohesin, and the CTCF anchors of ∼90% of the CTCF contact domains occur in a convergent orientation (Tang et al., 2015). These features suggest that CTCF contact domains are either insulated neighborhoods or clusters of insulated neighborhoods. Webto include CTCF and loops to define TADs, compartments play important role in the understanding of TAD interactions in a larger scale. Besides, contact domains, sub-TADs are classified into CTCF loop domains in which CTCF anchors halt the loop extrusion and ordinary domains which are not bound by CTCF proteins but specified by certain histone ...
