Recombinant Human EpoR

The erythropoietin receptor is a transmembrane protein belonging to the member of the cytokine receptor family. The receptor is tyrosine phosphorylated upon binding by erythropoietin and associates with and activates the tyrosine kinase, JAK2, which activates different intracellular pathways including: Ras/MAP kinase, phosphatidylinositol 3-kinase and STAT transcription factors. EPO-R transmits signals important for both proliferation and differentiation along the erythroid lineage.¹ Defects in the erythropoietin receptor may produce erythroleukemia and familial erythrocytosis.
