IL-4R alpha is a subunit alpha shared by IL-4 and IL-13 receptors, found in leukocytes originally. IL-4R alpha couples to the JAK1/2/3-STAT6 pathway and involves in promoting Th2 differentiation. IL-4R alpha/CD124, Mouse consists of 810 amino acids (M1-S810), exerts IL-4 binding function and results the phosphorylation of C-terminal tyrosine residues. IL-4R alpha/CD124, Mouse has an immunoreceptor tyrosine inhibitor motif (ITIM) (707-712 a.a), which can bind to the SH2 domain of some phosphatases by phosphorylating ITIM. IL-4R alpha/CD124, Mouse has a transmembrane domain (234-257 a.a). IL-4R alpha/CD124 Protein, Mouse (I26-R233) is produced in HEK293 cells, including a Fibronectin typr III domain (126-224 a.a) and a C-terminal hFC-tag.
