The protein recruits chromatin-remodeling factors in order to regulate chromatin structure and gene expression. [provided by RefSeq, Apr 2016]. COMPLETENESS: complete on the 3' end. * **UniProt Summary**: Crucial silencing factor contributing to the initiation of X inactivation mediated by Xist RNA that occurs during embryogenesis and in lymphoma (By similarity). Binds to DNA at special AT-rich sequences, the consensus SATB1-binding sequence (CSBS), at nuclear matrix- or scaffold-associated regions. Thought to recognize the sugar-phosphate structure of double-stranded DNA. Transcriptional repressor controlling nuclear and viral gene expression in a phosphorylated and acetylated status-dependent manner, by binding to matrix attachment regions (MARs) of DNA and inducing a local chromatin-loop remodeling. Acts as a docking site for several chromatin remodeling enzymes (e.g. PML at the MHC-I locus) and also by recruiting corepressors (HDACs) or coactivators (HATs) directly to promoters and enhancers. Modulates genes that are essential in the maturation of the immune T-cell CD8SP from thymocytes. Required for the switching of fetal globin species, and beta- and gamma-globin genes regulation during erythroid differentiation. Plays a role in chromatin organization and nuclear architecture during apoptosis. Interacts with the unique region (UR) of cytomegalovirus (CMV). Alu-like motifs and SATB1- binding sites provide a unique chromatin context which seems preferentially targeted by the HIV-1 integration machinery. Moreover, HIV-1 Tat may overcome SATB1-mediated repression of IL2 and IL2RA (interleukin) in T-cells by binding to the same domain than HDAC1. Delineates specific epigenetic modifications at target gene loci, directly up-regulating metastasis-associated genes while down-regulating tumor-suppressor genes. Reprograms chromatin organization and the transcription profiles of breast tumors to promote growth and metastasis. {ECO:0000250, ECO:0000269|PubMed:10595394, ECO:0000269|PubMed:11463840, ECO:0000269|PubMed:12374985, ECO:0000269|PubMed:12692553, ECO:0000269|PubMed:1505028, ECO:0000269|PubMed:15618465, ECO:0000269|PubMed:15713622, ECO:0000269|PubMed:16377216, ECO:0000269|PubMed:16630892, ECO:0000269|PubMed:17173041, ECO:0000269|PubMed:17376900, ECO:0000269|PubMed:18337816, ECO:0000269|PubMed:19103759, ECO:0000269|PubMed:19247486, ECO:0000269|PubMed:19332023, ECO:0000269|PubMed:19430959, ECO:0000269|PubMed:9111059, ECO:0000269|PubMed:9548713}. |CUT| |Homeobox| |activated T cell proliferation| |CD8-positive, alpha-beta T cell differentiation| |CD8-positive, alpha-beta T cell activation| |reflex| |nuclear heterochromatin| |CD4-positive, alpha-beta T cell differentiation| |T cell proliferation| |CD4-positive, alpha-beta T cell activation| |alpha-beta T cell differentiation| |alpha-beta T cell activation| |lymphocyte proliferation| |mononuclear cell proliferation| |histone methylation| |leukocyte proliferation| |PML body| |double-stranded DNA binding| |nuclear matrix| |protein alkylation| |protein methylation| |T cell differentiation| |chromatin remodeling| |T cell activation| |lymphocyte differentiation| |DNA-binding transcription repressor activity, RNA polymerase II-specific| |macromolecule methylation| |nuclear body| |methylation| |RNA polymerase II regulatory region sequence-specific DNA binding| |leukocyte differentiation| |histone modification| |covalent chromatin modification| |lymphocyte activation| |chromatin binding| |epidermis development| |cell population proliferation| |hemopoiesis| |hematopoietic or lymphoid organ development| |immune system development| |chromatin organization| |viral process| |symbiotic process| |interspecies interaction between organisms| |negative regulation of transcription by RNA polymerase II| |leukocyte activation| |chromosome organization| |cell activation| |negative regulation of transcription, DNA-templated| |negative regulation of nucleic acid-templated transcription| |negative regulation of RNA biosynthetic process| |negative regulation of RNA metabolic process| |negative regulation of cellular macromolecule biosynthetic process| |negative regulation of nucleobase-containing compound metabolic process| |negative regulation of macromolecule biosynthetic process| |negative regulation of cellular biosynthetic process| |negative regulation of biosynthetic process| |DNA-binding transcription factor activity, RNA polymerase II-specific| |negative regulation of gene expression| |tissue development| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp407|Thapsigargin 0.005μM R07 exp407]]|1.8| |[[:results:exp50|Nicotinamide 2000μM R01 exp50]]|1.82| |[[:results:exp504|MK2206 4μM R08 exp504]]|1.83| |[[:results:exp199|Etoposide 0.3μM R05 exp199]]|1.89| |[[:results:exp441|GSK-J4 1.5μM R08 exp441]]|1.94| No correlation found to any other genes in chemogenomics.
