Fc epsilon RI Antibody (9E1) Summary

Immunogen
Made to Human Fc EPSILON R1 ALPHA
Localization
Membrane; single pass type I membrane protein.
Specificity
NB100-63269 recognizes the human high affinity Fc receptor for IgE (Fc epsilon R1), which plays a central role in the IgE-mediated allergic response. Fc epsilon R1 consists of four subunits, a high affinity IgE binding alpha subunit, a beta chain and two di-sulphide linked gamma subunits. Clone 9E1 specifically recognizes the extracellular D1 domain of the Fc epsilon R1 alpha chain. Fc epsilon R1 is primarily expressed on mast cells and basophils but expression of Fc epsilon R1 has also been reported on monocytes, Langerhans cells and dendritic cells from patients with atopic diseases.

Background

The allergic reaction is mediated through the IgE high affinity receptor (FceRI). When a multivalent antigen is presented, a redistribution of the monomeric IgE FceRI receptor complexes cause the degranulation of mast cells and basophils, resulting in the subsequent release of factors responsible for the allergic reaction. The FceRI receptor is a tetrameric complex, consisting of a a-chain, b-chain and a dimeric g-chain. While the a-chain is primarily involved with the binding of IgE, the signal is transferred through the g subunit, which contains the immunoreceptor tyrosine activation motifs (ITAM) critical for initiating receptor mediated signal transduction through the Syk and Lyn tyrosine kinases. The FceRI receptor is able to engage and disengage the IgE, providing a versatile model for studying the function of kinase coupled receptors.
