Technical Data
ADAP (SLAP-130, Fyb, FYN Binding Protein, Adhesion and Degranulation Promoting Adaptor Protein, B630013F22Rik, FYB-120/130, FYN-binding Protein, FYN-T-binding Protein, p120/p130, SLP-76-associated Phosphoprotein)
FYB (FYN binding protein) was initially identified as a molecular adaptor that couples T cell receptor (TCR) stimulation to the avidity of integrins governing T cell adhesion. TCR stimulation promotes the formation of a multi-protein complex containing CARMA1, MALT1, and BCL-10, which through the association of FYB, ultimately activates the NFkB family of transcription factors. More recent experiments have shown that FYB controls optimal T cell proliferation, cytokine production, and expression of the Bcl-2 family member Bclx(L), suggesting that FYB regulates T cell activation by promoting antigen-dependent T cell-antigen presenting cell (APC) activation. At least three isoforms of FYB are known to exist.

Suitable for use in Western Blot and Immunoprecipitation. Other applications not tested.

Recommended Dilutions:
Western Blot: 0.5-2.0ug/ml detected ADAP/SLAP-130/Fyb in RIPA lysates from RAW 264.7 macrophage cells. RAW 264.7 cell lysate was resolved by electrophoresis, transferred to nitrocellulose and probed with A0859-43. Proteins were visualized using an IgG (HRP) goat anti-rabbit and a chemiluminescence detection system.
Immunoprecipitation: 4ug immunoprecipitated ADAP/SLAP-130/Fyb from 500ug of RAW 264.7 macrophage RIPA lysate.
Optimal dilutions to be determined by the researcher.

Recommended Secondary Antibodies:
I1904-39: IgG, X-Adsorbed (HRP) Pab Gt x Rb
