16220982-8	2005	Of the amino acids tested, leucine provided the highest affinity at pY+1 and its main chain NH is involved with a hydrogen bond with Stat3, presumably Ser636.	Leucine	27-34	signal transducer and activator of transcription 3	Homo sapiens	133-138	
21508089-14	2011	Leucine did not affect the mTOR pathway but did increase the phosphorylation states of PI3K, Akt, AMPK, p38 MAPK, JNK, GSK-3alpha/beta, STAT3, and STAT5 and increased cyclin D1 mRNA concentrations, which suggested that leucine may enhance cell proliferation.	Leucine	0-7	signal transducer and activator of transcription 3	Homo sapiens	136-141	
12746441-6	2003	On the other hand, Leu-411 of Stat3, corresponding to Leu-407 of Stat1, a necessary residue for Stat1 nuclear transport, is not essential for Stat3 nuclear import.	Leucine	19-22	signal transducer and activator of transcription 3	Homo sapiens	30-35	
12746441-6	2003	On the other hand, Leu-411 of Stat3, corresponding to Leu-407 of Stat1, a necessary residue for Stat1 nuclear transport, is not essential for Stat3 nuclear import.	Leucine	54-57	signal transducer and activator of transcription 3	Homo sapiens	30-35	
35280694-5	2022	The activation of Stat3 induced the secretion of glutamic acid-leucine-arginine (ELR) motif CXCLs (CXCL1, CXCL2, CXCL3 and CXCL8) in tumor cells.	Leucine	63-70	signal transducer and activator of transcription 3	Homo sapiens	18-23
