- | [[ | + | [[https://www.uniprot.org/uniprot/SATB1_HUMAN SATB1_HUMAN]] 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.<ref>PMID:1505028</ref> <ref>PMID:9111059</ref> <ref>PMID:9548713</ref> <ref>PMID:10595394</ref> <ref>PMID:11463840</ref> <ref>PMID:12374985</ref> <ref>PMID:12692553</ref> <ref>PMID:15618465</ref> <ref>PMID:15713622</ref> <ref>PMID:16377216</ref> <ref>PMID:16630892</ref> <ref>PMID:17376900</ref> <ref>PMID:17173041</ref> <ref>PMID:18337816</ref> <ref>PMID:19332023</ref> <ref>PMID:19430959</ref> <ref>PMID:19103759</ref> <ref>PMID:19247486</ref> |
