WebAug 1, 1999 · In this report, we have investigated the contribution of STAT5 to cellular transformation by the BCR/Abl oncogene. In K562 cells, we show that STAT5 (A and B) is constitutively phosphorylated on tyrosine and bind to a STAT5 binding site. Similarly, reporter constructs containing STAT5 binding sites are active in these cells.
