However, substitution of the Pro-X-Pro in the BOX1 motif with Ala-X-Ala failed to abolish IL-9 -induced cell proliferation but decreased IL-9 -mediated tyrosine phosphorylation of JAK kinases , insulin receptor substrate-2 , and signal transducer and activator of transcription 3 ( STAT3 ) and expression of c-myc and junB .
