After STAT5 binds the EPO:EPOR complex, phosphorylated JAK2 and LYN phosphorylate STAT5 (STAT5A or STAT5B) (Gouilleux et al. 1995, Pallard et al. 1995, Hoefsloot et al. 1997, Miura et al. 1998, Oda et al. 1998, Okajima et al. 1998, Erickson-Miller et al. 2000, and inferred from mouse homologs). STAT5A (MGH-STAT5) is phosphorylated on tyrosine-694 (Gouilleux et al. 1995, Arcasoy et al. 1999). Activation of STAT5 appears to be impaired in myelodysplastic syndrome (Hoefsloot et al. 1997). IGF-I enhances STAT5 phosphorylation in response to EPO (Okajima et al. 1998).
