Target Details for Fc epsilon RI/FCER1A

Target: Fc epsilon RI/FCER1A (FCER1A) (Fc Fragment of IgE Receptor Ia (FCER1A))

Background: FcεR1alpha is subunit of the high affinity receptor for IgE to which IgE directly binds. FcεR1alpha is a tetrameric complex consisting of one alpha, one beta and two γ subunits. The latter two are required for signal transduction activity. The FcεR1 complex plays an important role in triggering allergic responses. The CRA2 (AER24) monoclonal antibody reacts with the FcεR1alpha subunit on a region that overlaps the region of the IgE binding site, thus it competes with IgE for the receptor binding. Since the CRA1 (AER37) monoclonal antibody reacts with the site different from the IgE binding site on FcεR1alpha, it does not compete with IgE for the receptor binding. Combining the two antibodies, one can quantitatively measure the amounts of the IgE-bound FcεR1alpha.
