Primary antibody notes
Disabled 1 (Dab1) is an 80 kDa protein that is encoded by the Disabled 1 gene locus which is mutated in scrambler and yotari mutant mice. Phenotypically, the mutation of this gene produces motor defects and ataxia, disruption of neuronal migration, and severe cerebellar hypoplasia. Dab1 is an intracellular adapter protein that functions in downstream signaling events initiated by the secreted protein reelin. Dab1 contains a phosphotyrosine binding (PTB) domain in the amino terminus. Tyrosine phosphorylation of Dab1 is increased by reelin binding to the Very Low Density Lipoprotein Receptor (VLDLR) and Apolipoprotein E Receptor 2 (ApoER2) through stimulation of Src family kinases (e.g., Fyn). Src family kinase and c-Abl activities are themselves then stimulated by binding to tyrosine phosphorylated Dab1. Dab1 also mediates activation of Akt (PKB) by reelin resulting in inhibition of glycogen synthase kinase 3 beta (GSK-3 beta) and decreased phosphorylation of the microtubule-associated protein, Tau. Dab1 tyrosine 198 is a major site for reelin-induced Src family kinase-mediated phosphorylation in embryonic neurons.

Applications
Show applications key
Our Abpromise guarantee covers the use of ab5673 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
WB: 1/1000Detects a band of approximately 80 kDa.(When examining phosphorylation of endogenous Dab1 protein we recommend that Dab1 protein first be immunoprecipitated.)
Target
Function
Adapter molecule functioning in neural development. May regulate SIAH1 activity.
Sequence similarities
Contains 1 PID domain.
Domain
The PID domain specifically binds to the Asn-Pro-Xaa-Tyr(P) motif found in many tyrosine-phosphorylated proteins.
Post-translational
modifications
Phosphorylated on Tyr-198 and Tyr-220 upon reelin induction in embryonic neurons (By similarity). Also phosphorylated on Ser-524 independently of reelin signaling.

Western blot - Anti-Dab1 (phospho Y198) antibody (ab5673)
Mutant Analysis: Lysates prepared from HEK293 cells transfected with wild type (1, 2) or Y198F mutant mouse Dab1 (3, 4) and left untreated (-) (1, 3) or treated with H2O2 (+) (2, 4) were resolved by SDS-PAGE on a 10% polyacrylamide gel and transferred to PVDF. Membranes were blocked with a 5% BSA-TBST buffer overnight at 4°C, and incubated with ab5673 antibody for two hours at room temperature in a 3% BSA-TBST buffer. After washing, membranes were incubated with goat F(ab’)2 anti-rabbit IgG HRP conjugate and bands were detected using the Pierce SuperSignal method. The data show H2O2 stimulation of the phospho-Dab1 signal only in wild type Dab1-expressing cells. These results demonstrate the specificity of the ab5673 antibody for this site on the Dab1 protein.
