FceR1 alpha Antibody (PA5-80619) in ICC/IF
Immunofluorescence staining of FceR1 alpha in A549 cells. Cells were fixed with 4% PFA, blocked with 10% serum, and incubated with FceR1 alpha Polyclonal Antibody (Product # PA5-80619, 1:5,000) at 4°C overnight. Then cells were stained with the Alexa Fluor®594-conjugated Goat Anti-rabbit IgG secondary antibody (red) and counterstained with DAPI (blue). Positive staining was localized to cells membrane and c... View More

靶标信息
Fc epsilon RI alpha, also known as FceR1 alpha, is a subunit of the high-affinity receptor for IgE, primarily expressed on mast cells and basophils. Its expression is upregulated by the presence of IgE. Fc epsilon RI alpha forms a tetrameric complex with one beta and two gamma subunits, which are essential for signal transduction. The beta and gamma subunits contain immunoreceptor tyrosine-based activation motifs (ITAMs). The Fc epsilon RI complex plays a crucial role in triggering IgE-mediated allergic reactions. When allergen-bound IgE molecules bring together two or more high-affinity IgE receptors, it leads to the release of mediators such as histamine, which are responsible for allergy symptoms. This process couples allergens and mast cells to initiate inflammatory responses characteristic of allergic disorders like hay fever and asthma. The release of histamine and proteases also leads to the synthesis of prostaglandins and leukotrienes, which are potent effectors of the hypersensitivity response.
