Antibody Target Type: Phosphosite-specific

Antibody Phosphosite: Y1104

Protein UniProt: Q96RT1

Protein SigNET: Q96RT1

Antibody Type: Polyclonal

Antibody Host Species: Rabbit

Antibody Immunogen Source: Human ErbB2IP (Erbin) sequence peptide Cat. No.: PE-04AER99

Antibody Immunogen Sequence: EGD(pY)LSY(bA)C

Antibody Immunogen Description: Corresponds to amino acid residues E1101 to Y1107; In the C-terminal quarter of the protein before the PDZ domain. The major in vivo phosphorylation site in ErbB2IP.

Production Method: The immunizing peptide was produced by solid phase synthesis on a multipep peptide synthesizer and purified by reverse-phase hplc chromatography. Purity was assessed by analytical hplc and the amino acid sequence confirmed by mass spectrometry analysis. This peptide was coupled to KLH prior to immunization into rabbits. New Zealand White rabbits were subcutaneously injected with KLH-coupled immunizing peptide every 4 weeks for 4 months. The sera from these animals was applied onto an agarose column to which the immunogen peptide was thio-linked. Antibody was eluted from the column with 0.1 M glycine, pH 2.5. Subsequently, the antibody solution was neutralized to pH 7.0 with saturated Tris.This antibody was also subject to negative purification over phosphotyrosine-agarose.

Antibody Modification: Unconjugated. Contact KInexus if you are interest in having the antibody biotinylated or coupled with fluorescent dyes.

Scientific Background: ErbB2IP acts as an adapter for the receptor ErbB2, in epithelia. By binding the unphosphorylated 'Y1248' of receptor ErbB2, it may contribute to stabilize this unphosphorylated state. It Inhibits NOD2-dependent NF-kappa-B signalling and proinflammatory cytokine secretion.
