Catalog Number:

11709

Amount:

100μg

Price:

$319

Swiss-Prot No:

Swiss-Prot#: O95863;
NCBI Gene#: 6615;
NCBI Protein#: NP_005976.2.

Form of Antibody:

Rabbit IgG in phosphate buffered saline (without Mg2+ and Ca2+), pH 7.4, 150mM NaCl, 0.02% sodium azide and 50% glycerol.

Storage/Stability:

Immunogen:

Peptide sequence around phosphorylation site of Serine 246(T-F-S(p)-R-M) derived from Human SNAI1.

Purification:

Antibodies were produced by immunizing rabbits with synthetic phosphopeptide and KLH conjugates. Antibodies were purified by affinity-chromatography using epitope-specific phosphopeptide. Non-phospho specific antibodies were removed by chromatogramphy usi

Specificity/Sensitivity:

The antibody detects endogenous levels of SNAI1 only when phosphorylated at serine 246.

Applications:

WB IF

Background:

Involved in induction of the epithelial to mesenchymal transition (EMT), formation and maintenance of embryonic mesoderm, growth arrest, survival and cell migration. Binds to 3 E-boxes of the E-cadherin/CDH1 gene promoter and to the promoters of CLDN7 and KRT8 and, in association with histone demethylase KDM1A which it recruits to the promoters, causes a decrease in dimethylated H3K4 levels and represses transcription. Associates with EGR1 and SP1 to mediate tetradecanoyl phorbol acetate (TPA)-induced up-regulation of CDKN2B, possibly by binding to the CDKN2B promoter region 5'-TCACA-3. In addition, may also activate the CDKN2B promoter by itself.
