  • Function
    Binds to DNA, at nuclear matrix- or scaffold-associated regions. Thought to recognize the sugar-phosphate structure of double-stranded DNA. Transcription factor controlling nuclear gene expression, 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 and also by recruiting corepressors (HDACs) or coactivators (HATs) directly to promoters and enhancers. Required for the initiation of the upper-layer neurons (UL1) specific genetic program and for the inactivation of deep-layer neurons (DL) and UL2 specific genes, probably by modulating BCL11B expression. Repressor of Ctip2 and regulatory determinant of corticocortical connections in the developing cerebral cortex. May play an important role in palate formation. Acts as a molecular node in a transcriptional network regulating skeletal development and osteoblast differentiation.
  • Tissue specificity
    High expression in adult brain, moderate expression in fetal brain, and weak expression in adult liver, kidney, and spinal cord and in select brain regions, including amygdala, corpus callosum, caudate nucleus, and hippocampus.
  • Involvement in disease
    Note=Chromosomal aberrations involving SATB2 are found in isolated cleft palate. Translocation t(2;7); translocation t(2;11).
    Defects in SATB2 are a cause of cleft palate isolated (CPI) [MIM:119540]. A congenital fissure of the soft and/or hard palate, due to faulty fusion. Isolated cleft palate is not associated with cleft lips. Some patients may manifest other craniofacial dysmorphic features, mental retardation, and osteoporosis.
    Note=A chromosomal aberration involving SATB2 is found in a patient with classical features of Toriello-Carey syndrome. Translocation t(2;14)(q33;q22).
  • Sequence similarities
    Belongs to the CUT homeobox family.
    Contains 2 CUT DNA-binding domains.
    Contains 1 homeobox DNA-binding domain.
  • Post-translational
    Sumoylated by PIAS1. Sumoylation promotes nuclear localization, but represses transcription factor activity.
  • Cellular localization
    Nucleus matrix.

Of the two rabbit monoclonals, ab92446 (SATB2) and ab92307 (SATB1), ab92446 is more likely to be specific for its target, SATB2, than ab92307 is for SATB1.

Click here (or use the following: https://www.abcam.com/index.html?datasheet=92446).

Click here (or use the following: https://www.abcam.com/index.html?datasheet=92307).

Alignments of the immunogens for each with the related protein returned 57% and 73% identity.

The immunogen for ab92446 anti-SATB2 was aligned with human SATB1 (UniProt Q01826) and the result was 4/7 (57%) over a 7 amino acid range.

The immunogen for ab92307 anti-SATB1 was aligned with human SATB2 (UniProt Q9UPW6) and the result was 11/15 (73%).

You mentioned in an earlier message that you were concerned that the antibodies ab51502 and ab92307 were not specific for the proteins SATB2 and SATB1, respectively:

"...However, I have encountered a problem when I conducted an IHC experiment. I was not convinced that the antibodies were distinguishing between SATB1 and SATB2"

Was that concern based on experimental evidence?

Thank you for sending the catalogue abID's.

The alignments of the immunogens with the other proteins do suggest that these antibodies may not have the specificity you hope for:

The ab92307 immunogen shares 73% identity (11/15) with human SATB2, Uniprot Q9UPW6.

The ab51502 immunogen shares 70% (72/103) identity with human SATB1, Uniprot Q01826.

I hope this helps. Please let me know if you have any questions.

Thank you for contacting us. The concentration of ab51502 is 0.1 mg/ml and should be used at a dilution of 1/100 for both IP and WB. Regarding ab92445, this is a tissue culture supernatant antibody so the concentration is not determined. Generally concentrations are only determined for purified antibodies as they are not relevant for other types that may contains proteins other than the protein of interest. This product should be used at a dilution of 1/10-1/100 for IP and 1/1000-1/10000 for WB. We do not test our antibodies side by side and cannot say which works "better" for a particular application but we do guarantee them both to work in IP and WB.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
