Immunofluorescence analysis of EPO Receptor [pYpY454/456] was done on 70% confluent log phase HeLa cells. The cells were fixed with 4% paraformaldehyde for 15 minutes, permeabilized with 0.25% Triton™ X-100 for 10 minutes, and blocked with 5% BSA for 1 hour at room temperature. The cells were labeled with ABfinity™ EPO Receptor [pYpY454/456] Recombinant Rabbit Oligoclonal Antibody (710484) at a dilution of 1:500 in 1% BSA and incubated for 3 hours at room temperature and then labeled with Alexa Flour® 488 Goat Anti-Rabbit IgG Secondary Antibody (A11008) at a dilution of 1:400 for 30 minutes at room temperature (Panel a: green). F-actin (Panel b: red) was stained with Alexa Fluor® 594 Phalloidin (A12381). Nuclei (Panel c: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (S36938). Panel d is a merged image showing cytoplasmic and membrane localization. Panel e shows competition with the phospho- EPO R [pYpY454/456] peptide. The images were captured using Nikon enabled with cool snap at 20X magnification.

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.
