LP36006-2 Fc epsilon RI
The high-affinity IgE receptor, also known as FcεRI, or Fc epsilon RI, is the high-affinity receptor for the Fc region of immunoglobulin E (IgE), an antibody isotype involved in the allergy disorder and parasites immunity. FcεRI is a tetrameric receptor complex consisting of one alpha (FcεRIα - antibody binding site), one beta (FcεRIβ - which amplifies the downstream signal), and two disulfide bridge connected gamma chains (FcεRIγ - the site where the downstream signal initiates). It is constitutively expressed on mast cells and basophils and is inducible in eosinophils.
FcεRI is found on epidermal Langerhans cells, eosinophils, mast cells, and basophils. As a result of its cellular distribution, this receptor plays a major role in controlling allergic responses. FcεRI is also expressed on antigen-presenting cells, and controls the production of important immune mediators (cytokines, interleukins, leukotrienes, and prostaglandins) that promote inflammation. The most famous mediator is histamine, which results in the five symptoms of inflammation: heat, swelling, pain, redness and itchiness.
