16764840-4	2006	Furthermore, the phosphorylation of STAT3 on tyrosine and serine residues was analyzed at these different stages by immunoprecipitation followed by Western blot.	Tyrosine	45-53	signal transducer and activator of transcription 3	Rattus norvegicus	36-41	
16764840-7	2006	Phosphorylation on tyrosine and serine was observed at P3 and increased at P10, which suggests an augmented activation of STAT3 at the mid-postnatal period.	Tyrosine	19-27	signal transducer and activator of transcription 3	Rattus norvegicus	122-127
