Structures of natural cytotoxicity receptors. Structures of natural cytotoxicity receptors. (A) Structure of NKp30 adopts an I-type Ig-fold with β strands labeled and disulphide bonds shown in stick representation colored yellow. The common Ig-fold disulfide bond is formed between Cys-39 and Cys-108. (B) C-alpha ribbon representation of NKp30 with every 10th residue indicated by a sphere. (C) Structure of NKp44 displays a typical V-type Ig-fold with distinct regions different from NKp30 colored in red; disulphide bonds are shown in stick representation colored yellow. (D) Cartoon representation of NKp46 with β strands labeled. M. Gordon Joyce et al. PNAS 2011;108:15:6223-6228 ©2011 by National Academy of Sciences
