Molecular Characterization: IL4RA(Met26-His232)6A-His tagMolecular weight: The protein has a predicted molecular mass of 24.6 kDa after removal of the signal peptide.The apparent molecular mass of IL4RA-His is approximately 35-55 kDa due to glycosylation.Description: Recombinant human IL4RA protein with C-terminal6A-His tagThis gene encodes the alpha chain of the interleukin-4 receptor, a type I transmembrane protein that can bind interleukin 4 and interleukin 13 to regulate IgE production. The encoded protein also can bind interleukin 4 to promote differentiation of Th2 cells. A soluble form of the encoded protein can be produced by proteolysis of the membrane-bound protein, and this soluble form can inhibit IL4-mediated cell proliferation and IL5 upregulation by T-cells. Allelic variations in this gene have been associated with atopy, a condition that can manifest itself as allergic rhinitis, sinusitus, asthma, or eczema. Polymorphisms in this gene are also associated with resistance to human immunodeficiency virus type-1 infection. Alternate splicing results in multiple transcript variants.
