UniProtKB description:  Insulator DNA-binding protein (PubMed:25342723). Chromatin insulators are regulatory elements that establish independent domains of transcriptional activity within eukaryotic genomes. Insulators are proposed to structure the chromatin fiber into independent domains of differing transcriptional potential by promoting the formation of distinct chromatin loops to form topologically associating domains (TADs). Recruits Cp190 and cooperatively binds to chromatin promoter and insulator regions to exert transcriptional regulator and chromatin insulator functions (PubMed:25342723, PubMed:33752739). Recruitment of Cp190 leads to recruitment of Chro/chromator and chromatin decondensation (PubMed:33752739). Chromatin binding sites often cluster with those of other insulator DNA binding proteins that can recruit Cp190, such as ZIPIC, CTCF, BEAF-32, lbf1, lbf2, insv/insensitive and, to a lesser extent, Su(Hw) (PubMed:25342723, PubMed:33752739). Together with Cp190 and CTCF involved in regulation of the Miscadastral pigmentation (MCP) insulator (PubMed:25342723).
