Proteomics (Proteome ID):

Erythropoietin receptor (EPO-R)

Proteomics (Chromosome):

UP000005640

Mass Spectrometry:

N/A

Function [CC]:

Receptor for erythropoietin. 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.

Metal Binding:

N/A

Site:

SITE 117 117 Required for ligand binding.; SITE 368 368 Interaction with APS and STAT5, and activation. {ECO:0000250}.; SITE 426 426 Required for STAT5/PTPN11/SOCS3 binding. {ECO:0000250}.; SITE 454 454 Interaction with PTPN6. {ECO:0000250}.; SITE 456 456 Required for STAT1/STAT3 activation.; SITE 485 485 Required for CrkL binding. {ECO:0000250}.

Tissue Specificity:

Erythroid cells and erythroid progenitor cells. Isoform EPOR-F is the most abundant form in EPO-dependent erythroleukemia cells and in late-stage erythroid progenitors. 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.

Disease:

Erythrocytosis, familial, 1 (ECYT1) [MIM:133100]: An autosomal dominant disorder characterized by increased serum red blood cell mass, elevated hemoglobin and hematocrit, hypersensitivity of erythroid progenitors to erythropoietin, erythropoietin low serum levels, and no increase in platelets nor leukocytes. It has a relatively benign course and does not progress to leukemia. {ECO:0000269|PubMed:8506290, ECO:0000269|PubMed:8608241}. Note=The disease is caused by mutations affecting the gene represented in this entry.
