Datasheet

MSDS

Human erythropoietin receptor (EpoR) is a transmembrane protein found on the surface of erythropoietin (Epo) responding cells and functions as a homodimer. The recombinant EpoR dimer protein (CSP-24087) is a cis-homodimer (cis-dimer) and contains an EpoR extracellular domain (UniProt# P19235, amino acids Ala25-Pro250) fused with a proprietary dimer motif followed by a tandem His-Avi tag at the C-terminus. This dimeric protein is expressed in HEK293T cells. The recombinant human EpoR dimer protein is bioactive and can bind to erythropoietin (Epo). It also binds EpoR-specific antibodies. This EpoR dimer can be used as an antigen for in vitro assays and antibody screening, and as an immunogen for immunization to generate antibodies targeting more conformational epitopes.

Background and Alternate Names

Human erythropoietin receptor (EpoR), also known as EPO-R and CD131, is a transmembrane protein found on the surface of erythropoietin (Epo) responding cells. EpoR belongs to the type I cytokine receptor family. EpoR contains an extracellular domain with two fibronectin type II domains, a transmembrane domain, a juxtamembrane region, and a cytoplasmic region. It functions as a homodimer to form an active receptor complex upon ligand binding that is crucial for receptor activation and downstream signaling. EpoR dysregulation is involved in blood disorders including the development of erythroleukemia and familial erythrocytosis. Therefore, a recombinant protein mimicking the EpoR dimer conformation can be crucial for therapeutic discovery.
