mouse monoclonal IgG1; SATB1 Antibody (C-6) is an IgG1 κ mouse monoclonal SATB1 antibody (also designated Special AT-Rich Sequence Binding Protein 1 (Binds To Nuclear Matrix/Scaffold-Associating DNA) antibody, DNA-Binding Protein SATB1 antibody, or Special AT-Rich Sequence-Binding Protein 1 antibody) that detects the SATB1 protein of mouse, rat and human origin by WB, IP, IF, IHC(P) and ELISA. SATB1 Antibody (C-6) is available as both the non-conjugated anti-SATB1 antibody form, as well as multiple conjugated forms of anti-SATB1 antibody, including agarose, HRP, PE, FITC and multiple Alexa Fluor® conjugates. The homeoproteins CCAAT displacement protein (CDP) and special AT-rich sequence binding protein 1 (SATB1) are transcriptional repressors of many cellular genes, and they participate in cell development and cell type differentiation. SATB1 is expressed primarily in thymocytes, and, like CDP, it also contains a distinct homeobox DNA-binding domain that is essential for DNA binding. SATB1 and CDP interact through these homeodomains and synergistically function as mediators of gene expression. SATB1 contains an additional domain that has a higher affinity for DNA and specifically facilitates the direct association between SATB1 and the nuclear matrix attachment regions (MARs) of DNA. MARs are specific DNA sequences that bind to the nuclear matrix and form the base of chromosomal loops that organize the chromosomes and regulate DNA transcription and replication within the nucleus. The association of SATB1 with the core unwinding element within the base-unpairing region of MARs requires both the MAR and homeobox binding domains of SATB1.
