Additional Info
| Tissue Specificity | Erythroid cells and erythroid progenitor cells. Isoform EPOR-F: Isoform EPOR-F is the most abundant form in EPO-dependent erythroleukemia cells and in late-stage erythroid progenitors. Isoform EPOR-S: Isoform EPOR-S and isoform EPOR-T are the predominant forms in bone marrow. Isoform EPOR-T: Isoform EPOR-S and isoform EPOR-T are the predominant forms in bone marrow. Isoform EPOR-T is the most abundant from in early-stage erythroid progenitor cells. |
| Post Translational Modifications | On EPO stimulation, phosphorylated on C-terminal tyrosine residues by JAK2. The phosphotyrosine motifs are also recruitment sites for several SH2-containing proteins and adapter proteins which mediate cell proliferation. Phosphorylation on Tyr-454 is required for PTPN6 interaction, Tyr-426 for PTPN11. Tyr-426 is also required for SOCS3 binding, but Tyr-454/Tyr-456 motif is the preferred binding site. Ubiquitinated by the ECS(SOCS2) complex following ligand-binding and phosphorylation by JAK2, leading to its degradation by the proteasome. Regulation by the ECS(SOCS2) complex acts as a negative feedback loop of erythropoietin-mediated signaling pathway. Ubiquitination at Lys-281 mediates receptor internalization, whereas ubiquitination at Lys-453 promotes trafficking of activated receptors to the lysosomes for degradation. Ubiquitinated by NOSIP.appears to be either multi-monoubiquitinated or polyubiquitinated. Ubiquitination mediates proliferation and survival of EPO-dependent cells. |
| Function | Receptor for erythropoietin, which mediates erythropoietin-induced erythroblast proliferation and differentiation. Upon EPO stimulation, EPOR dimerizes triggering the JAK2/STAT5 signaling cascade. In some cell types, can also activate STAT1 and STAT3. May also activate the LYN tyrosine kinase. Isoform EPOR-T: Acts as a dominant-negative receptor of EPOR-mediated signaling. |
