17132731-4	2006	The HCCH motif is involved in stabilizing the Vif-Cullin 5 interaction, but the exact role of the conserved His and Cys residues remains elusive.	alpha-hexachlorocyclohexane	4-8	cullin 5	Homo sapiens	50-58	
16636053-6	2006	Mutations of His/Cys residues in the HCCH motif impair zinc coordination, Cul5 binding, and APOBEC3G degradation.	alpha-hexachlorocyclohexane	37-41	cullin 5	Homo sapiens	74-78	
16636053-10	2006	We propose that the HCCH zinc-binding motif facilitates Vif-Cul5 binding by playing a structural role in positioning hydrophobic residues for direct contact with Cul5.	alpha-hexachlorocyclohexane	20-24	cullin 5	Homo sapiens	60-64
