3 Although studies with truncated erythropoietin receptors (EpoRs) have suggested the tyrosine phosphorylation (Yphos) of the EpoR may not play a significant role in Epo-induced proliferation, we found, using a full length EpoR mutant designed Null, in which all 8 of the intracellular tyrosines (Ys) were substituted with phenylalanines (Fs), that Null cells required 5-10 fold more Epo than wild type (WT) EpoR containing cells in order to proliferate as well.
