28869519-6	2017	A cleft containing the predicted sulfotyrosine-binding pocket was identified as a principal hot spot for ligand binding on the structures of CXCL1, CXCL2, CXCL7, and CXCL8, but not CXCL5.	tyrosine O-sulfate	33-46	C-X-C motif chemokine ligand 1	Homo sapiens	141-146	
23269549-3	2013	hGRO-alpha binds vGPCR in a sulfotyrosine-dependent manner and promotes its tumorigenicity through autocrine signaling.	tyrosine O-sulfate	28-41	C-X-C motif chemokine ligand 1	Homo sapiens	0-10	
20106924-4	2010	A chemokine-binding assay demonstrated that the tyrosine sulfate moieties were critical for vGPCR association with GRO-alpha (an agonist) but not with IP-10 (an inverse agonist).	tyrosine O-sulfate	48-64	C-X-C motif chemokine ligand 1	Homo sapiens	115-124	
20106924-9	2010	Indeed, GRO-alpha increased vGPCR-mediated AKT phosphorylation and vGPCR tumorigenesis in a sulfotyrosine-dependent manner.	tyrosine O-sulfate	92-105	C-X-C motif chemokine ligand 1	Homo sapiens	8-17
