Directly binds the telomeric double-stranded 5'-TTAGGG-3' repeat (PubMed:28500257, PubMed:28082411). Preferentially binds to telomeres that have a low concentration of shelterin complex and acts as a regulator of telomere length by initiating telomere trimming, a process that prevents the accumulation of aberrantly long telomeres (PubMed:28082411). Also acts as a transcription regulator that binds to promoter regions (PubMed:7969177, PubMed:24382891, PubMed:28500257). Regulates expression of a small subset of genes, including MTFP1 (PubMed:28500257). Regulates expression the J and/or S elements in MHC II promoter (PubMed:7969177). Acts as a negative regulator of cell proliferation by specifically activating expression of ARF, a tumor suppressor isoform of CDKN2A (PubMed:24382891). {ECO:0000269|PubMed:24382891, ECO:0000269|PubMed:28082411, ECO:0000269|PubMed:28500257, ECO:0000269|PubMed:7969177}. |BTB| |double-stranded telomeric DNA binding| |telomere maintenance via telomere lengthening| |chromosome, telomeric region| |telomere maintenance| |telomere organization| |transcription regulatory region DNA binding| |anatomical structure homeostasis| |DNA-binding transcription factor activity| |DNA metabolic process| |chromosome organization| |identical protein binding| |positive regulation of transcription, DNA-templated| |DNA-binding transcription factor activity, RNA polymerase II-specific| |positive regulation of nucleic acid-templated transcription| |positive regulation of RNA biosynthetic process| |homeostatic process| |positive regulation of RNA metabolic process| |positive regulation of nucleobase-containing compound metabolic process| |positive regulation of macromolecule biosynthetic process| |positive regulation of cellular biosynthetic process| |positive regulation of gene expression| |positive regulation of biosynthetic process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp269|Bisphenol A 100μM R06 exp269]]|-2.73| |[[:results:exp111|R-DABN 8μM R03 exp111]]|-2.22| |[[:results:exp11|CCCP 1μM R00 exp11]]|-2.07| |[[:results:exp524|Staurosporine 0.02μM R08 exp524]]|1.74| |[[:results:exp435|JQ1 0.8μM R08 exp435]]|1.76| |[[:results:exp90|WYE-354 6μM R02 exp90]]|2.07| No correlation found to any other genes in chemogenomics.
