The public catalogues list it as a tumour suppressor and a biomarker, and clinical evidence ties its variants to diagnosis, prognosis or drug response. Tied to Endometrial cancer, Breast cancer, Head and neck squamous cell carcinoma and 4 more.","summary":"Chromatin binding factor that binds to DNA sequence specific sites and regulates the 3D structure of chromatin. Binds together strands of DNA, thus forming chromatin loops, and anchors DNA to cellular structures, such as the nuclear lamina. Defines the boundaries between active and heterochromatic DNA via binding to chromatin insulators, thereby preventing interaction between promoter and nearby enhancers and silencers.\n\nCIViC holds 3 clinical evidence items and 0 assertions across 3 variants. Open Targets scores its association with cancer at 0.76 (direct and indirect evidence; datatypes literature 0.99, genetic association 0.00, somatic mutation 0.91).

Participates in the allele-specific gene expression at the imprinted IGF2/H19 gene locus. On the maternal allele, binding within the H19 imprinting control region (ICR) mediates maternally inherited higher-order chromatin conformation to restrict enhancer access to IGF2. Mediates interchromosomal association between IGF2/H19 and WSB1/NF1 and may direct distant DNA segments to a common transcription factory.
