Description
IL-5R alpha protein is a cytokine receptor that is expressed on eosinophils, basophils and B cells and is involved in inflammation and immune regulation.IL-5R alpha Protein, Human (HEK293, His-Avi) is expressed by HEK293 cells with His-Avi tags[1][3].
Background
IL-5R alpha is a type I cytokine receptor consisting of two distinct polypeptide chains, alpha and beta. alpha chain is a membrane-penetrating glycoprotein that specifically binds IL-5 and beta chain converts low affinity IL-5R to high affinity IL-5R, forming a heterodimeric receptor complex[1].
IL-5R alpha can induce the activation of multiple intracellular signalling pathways, including JAK/STAT, RAF/MAP, Ras-Raf-ERK and phosphatidylinositol 3-kinase when its binds with IL-5[2].
IL-5R alpha is expressed on eosinophils, basophils and B cells and affects cell survival, apoptosis, differentiation and chemotaxis[3].
