  ABSTRACT  
 
The Ly49 family of natural killer (NK) receptors regulates NK cell function by sensing major histocompatibility complex (MHC) class I. Ly49 receptors show complex patterns of MHC class I cross-reactivity and, in certain cases, peptide selectivity. To investigate whether specificity differences result from topological differences in MHC class I engagement, we determined the structure of the peptide-selective receptor Ly49C in complex with H-2K(b). The Ly49C homodimer binds two MHC class I molecules in symmetrical way, a mode distinct from that of Ly49A, which binds MHC class I asymmetrically. Ly49C does not directly contact the MHC-bound peptide. In addition, MHC crosslinking by Ly49C was demonstrated in solution. We propose a dynamic model for Ly49-MHC class I interactions involving conformational changes in the receptor, whereby variations in Ly49 dimerization mediate different MHC-binding modes.

Figure 2.
Figure 2. Structure of Ly49/MHC class I complexes. (a) Superposition of wild-type (blue) and mutant (red) Ly49C -H-2Kb complexes in the crystallographic asymmetric unit, indicating close overall similarity. (b) Electron density in the interface of the mutant Ly49C -H-2Kb complex. The F[o] - F[c] omit map at 2.9 resolution is contoured at 2.5 . Ly49C residues 239 -243 (red), H-2Kb heavy chain residues 111 -117 (blue) and [2]M residues 58 -60 (yellow) were excluded from the map calculation. (c) Ribbon diagram of the mutant Ly49C -H-2Kb complex, in which the crystallographic Ly49C dimer (red) crosslinks two MHC class I molecules. (d) Structure of the Ly49A -H-2D^d complex, showing the asymmetric interaction between the Ly49A dimer (green) and two MHC class I molecules. The two interaction surfaces, site 1 and site 2, are indicated by the dashed circle and rectangle, respectively. In c and d, the H-2Kb heavy chain is blue, the ovalbumin peptide (ball-and-stick representation) is red and [2]M is yellow.

Figure 6. Comparison of hydrogen-bonding networks at the Ly49C -H-2Kb and Ly49A -H-2D^d interfaces. (a) Detailed view (stereo diagram) of the Ly49C -H-2Kb interface showing hydrogen bonds (dotted black lines) between Ly49C (red) and the H-2Kb heavy chain (blue) or [2]M (violet); the side chains of interacting residues are yellow. The portion of the Ly49C L3 loop, encompassing residues 226 -231, which is disordered in both mutant and wild-type structures, is drawn arbitrarily (red balls). With the exception of H-2Kb residues Asp212 and Thr214, whose side chains could potentially interact with the disordered L3 loop of Ly49C, only residues forming hydrogen bonds are shown. (b) Stereo diagram showing hydrogen bonds between Ly49A (green) and the H-2D^d heavy chain (blue) or [2]M (violet) at the site 2 interface of the Ly49A -H-2D^d complex.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB codes are shown on the right.
