Synthetic phosphopeptide conjugated to KLH, corresponding to amino acid residues around tyrosine 1526 of human integrin-beta4.
The cytoplasmic domain of the integrin-ß4 subunit recruits the adaptor protein Shc and is required for assembly of hemidesmosomes. Tyrosine phosphorylation of multiple sites within the cytoplasmic domain regulates these cellular events. In particular, tyrosine 1526 interacts with the phosphotyrosine binding domain of Shc and is required for Shc activation. In addition, tyrosine 1494 is required for integrin-mediated IRS-2 phosphorylation and activation of PI3-kinase. More importantly, this site is critical for integrin a6ß4 increases in carcinoma invasion.
