Allergin-1 Protein, an immunoglobulin-like receptor, crucially acts as a negative regulator in mast cells, inhibiting degranulation. Operating as a monomer, it interacts with signaling molecules like tyrosine-phosphorylated PTPN6, PTPN11, and INPP5D, forming complexes that suppress IgE-mediated mast cell activation, thus dampening type I immediate hypersensitivity reactions. Allergin-1 Protein, Human (HEK293, Fc) is the recombinant human-derived Allergin-1 protein, expressed by HEK293 , with C-hFc labeled tag.
