Supplementary information

SATB1 or Special AT-rich Sequence Binding Protein 1 is a nuclear matrix-associated protein with a mass of approximately 85 kDa. It modifies chromatin structure by organizing the density of DNA through loop formation which regulates gene expression. SATB1 is expressed in thymocytes breast tissue and various other cell types and plays a significant role in cellular differentiation and development. It binds selectively to base-unpairing regions allowing it to influence expression patterns of multiple genes.
Biological function summary

SATB1 acts as a genome organizer and transcription regulator by linking chromatin remodeling complexes to specific genomic loci. It participates in chromatin loop domain organization influencing higher-order chromatin structure and gene silencing or activation. SATB1 does not usually work alone but rather associates with corepressors such as HDAC1 and coactivators like PCAF in regulating transcription. Its functions have been noted as particularly important in T cell development where it assists in the regulation of T cell receptor genes.

Pathways

SATB1 integrates into the Wnt signaling pathway and influences the Notch signaling pathway. The protein interacts with Β-catenin in the Wnt pathway aiding in sustaining key developmental processes. In the Notch signaling pathway SATB1 influences cell fate decisions impacting differentiation and proliferation through its interaction with RBP-Jκ and other transcription modulators. MUTYH and LRP6 are among the proteins within these pathways influenced by SATB1's regulatory capacity.

SATB1 links to various cancer types including breast cancer and colorectal cancer. Overexpression of SATB1 can drive tumor progression and metastasis by altering gene expression landscapes. It's known to affect pathways regulated by proteins like BRCA1 in breast cancer contributing to disease pathogenicity. In immune disorders such as autoimmune diseases SATB1 interacts with STAT5 impacting cytokine signaling pathways and thereby influencing immunological tolerance and efficacy.

Target data

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. Promotes neuronal differentiation of neural stem/progenitor cells in the adult subventricular zone, possibly by positively regulating the expression of NEUROD1 (By similarity).
