2648385-3	1989	By a combination of Edman degradation and mass spectrometry, it was established that GDCF-2 comprises 76 amino acid residues, commencing at the N terminus with pyroglutamic acid.	Pyrrolidonecarboxylic Acid	160-177	C-C motif chemokine ligand 2	Homo sapiens	85-91	
2648385-6	1989	Thus, GDCF and MDNCF have a similar gross secondary structure because of the loops formed by the clustered disulfides, and their different leukocyte specificities are most likely determined by the large differences in primary sequence.	Disulfides	107-117	C-X-C motif chemokine ligand 8	Homo sapiens	15-20
