MHC class I antigen

Intermolecular
Cysteine 188 and cysteine 302 of BSLF2/BMLF1 protein
Intramolecular
Cysteine 125 and cysteine 188
Cysteine 227 and cysteine 283
A redox-regulated disulphide may form between cysteine 188 of MHC class I antigen and cysteine 302 of BSLF2/BMLF1 protein (164 and 3 respectively in this structure). However, the redox score of this cysteine pair is lower than any known redox-active intermolecular disulphide. ?
