In the present study we demonstrate that also the signal transducers and activators of transcription (STAT) family members STAT1 p91 and STAT3 p92 and the product of the c-fps/fes protooncogene become tyrosine -phosphorylated upon GM-CSF stimulation and physically associated with both GM-CSF receptor beta common subunit and JAK2 .
