16285718-7	2005	Rituximab binding is abolished by reduction and alkylation of CD20, with data consistent with the proposed antibody epitope being within the disulfide-bonded loop formed between cysteine residues 167 and 183.	Cysteine	178-186	keratin 20	Homo sapiens	62-66

19053310-0	2008	Site-specific, thiol-mediated conjugation of fluorescent probes to cysteine-modified diabodies targeting CD20 or HER2.	Cysteine	67-75	keratin 20	Homo sapiens	105-109	
16285718-9	2005	Antibody binding is unaffected by mutations of cysteines proposed to be in the intracellular domain of CD20.	Cysteine	47-56	keratin 20	Homo sapiens	103-107	
8899501-7	1996	CD20-cy+ B cells were seen mainly in the portal areas, and were significantly less common in AHB than in AHA and AHC.	Cysteine	5-7	keratin 20	Homo sapiens	0-4
