9558728-11	1998	In addition to the tyrosine phosphorylation we have observed that IL-6 also induces a serine phosphorylation of STAT3.	Serine	86-92	interleukin 6	Homo sapiens	66-70	
9558728-13	1998	We propose that the STAT3 serine phosphorylation is required for transactivation of IL-6 target genes which is also inhibited by H7.	Serine	26-32	interleukin 6	Homo sapiens	84-88
