Background Information

Fc epsilon Receptor I alpha (FceR1a) is a single-pass type I membrane protein that contains 2 immunoglobulin-like domains. FceR1a forms a tetrameric complex, FceRI, with one beta and two gamma subunits (PMID: 19406478). FceRI is the high-affinity receptor for the Fc region of immunoglobulin E (IgE) (PMID: 1532373). It is expressed on mast cells and basophils and plays a central role in the allergic response (PMID: 2148316). The calculated molecular weight of FceR1a is 30 kDa, the 55- to 70-kDa bands detected by this antibody are probably caused by heterogeneous glycosylation (PMID: 11344350; 12671054).
