NCIt definition : Interleukin-13 receptor subunit alpha-1 (427 aa, 49 kDa) is encoded by the human
IL13RA1 gene. This protein is involved in cytokine-mediated signal transduction.;
NCIt note : This protein is a subunit of the interleukin 13 receptor. This subunit forms a receptor
complex with IL4 receptor alpha, a subunit shared by IL13 and IL4 receptors. This
subunit serves as a primary IL13-binding subunit of the IL13 receptor, and may also
be a component of IL4 receptors. This protein has been shown to bind tyrosine kinase
TYK2, and thus may mediate the signaling processes that lead to the activation of
JAK1, STAT3 and STAT6 induced by IL13 and IL4.;
