Cysteine 18-26 chromobox 5 Homo sapiens 285-288 25267718-4 2014 Using copper(II) (1,10-phenanthroline)3 (CuPh) for cross-linking cysteine pairs, we found strong inhibition of transport when A243C (TM4) was combined with S366C (HP1), I453C (HP2), or T456C (HP2). Cysteine 65-73 chromobox 5 Homo sapiens 163-166 20675861-3 2010 Here, we have identified intermolecular disulfide bond formation of HP1 cysteines in an isoform-specific manner. Cysteine 72-81 chromobox 5 Homo sapiens 68-71 20675861-4 2010 Cysteine 133 in HP1alpha and cysteine 177 in HP1gamma were involved in intermolecular homodimerization. Cysteine 0-8 chromobox 5 Homo sapiens 16-24 20675861-5 2010 Although both HP1alpha and HP1gamma contain reactive cysteine residues, only HP1gamma readily and reversibly formed disulfide homodimers under oxidative conditions. Cysteine 53-61 chromobox 5 Homo sapiens 14-22 2019582-1 1991 HP-1 is a 30-residue cysteine- and arginine-rich peptide of the human neutrophil primary granule and is the most abundant human representative of the family of peptides variously called defensins and corticostatins. Cysteine 21-29 chromobox 5 Homo sapiens 0-4
