Transcript
Erythropoietin (EPO) binds to Erythropoietin Receptor (EPO-R) on Erythrocyte
Progenitor Cells
Erythropoietin (EPO) binding induces conformational changes to occur in
Erythropoietin Receptor (EPO-R)
Activation of Janus Kinase (JAK) occurs
Janus Kinase (JAK) activates its substrate, STAT5, a transcription factor
Activated STAT5 translocates into the nucleus
STAT5 binds to promoter elements of proliferation-inducing genes
Expression of proliferation-inducing genes
Increased production of Red Blood Cells
