Crystal structure of HLA-A2 bound to LIR-1, a host and viral major histocompatibility complex receptor.

  ABSTRACT  
 
Leukocyte immunoglobulin-like receptor 1 (LIR-1), an inhibitory receptor expressed on monocytes, dendritic cells and lymphocytes, regulates cellular function by binding a broad range of classical and nonclassical major histocompatibility complex (MHC) class I molecules, and the human cytomegalovirus MHC class I homolog UL18. Here we describe the 3.4-A crystal structure of a complex between the LIR-1 D1D2 domains and the MHC class I molecule HLA-A2. LIR-1 contacts the mostly conserved beta(2)-microglobulin and alpha3 domains of HLA-A2. The LIR-1 binding site comprises residues at the interdomain hinge, and a patch at the D1 tip. The structure shows how LIR-1 recognizes UL18 and diverse MHC class I molecules, and indicates that a similar mode of MHC class I recognition is used by other LIR family members.

Figure 4. Implications of UL18 -LIR-1 interaction. (a) View of D1D2 -HLA-A2 structure with the approximate positions of potential UL18 glycosylation sites mapped onto the HLA-A2 structure. Potential N-linked glycosylation sites (pink spheres) are distant from the LIR-1 binding site. The closest predicted O-linked glycosylation site (gray sphere) is also distant from the binding site. Three additional O-linked glycosylation sites are predicted in UL18 in a region corresponding to sequence between the carboxyl terminus of the HLA-A2 ectodomain and the transmembrane region. (b) Closer view of the LIR-1 -HLA-A2 interface in the region outlined by the dotted rectangle in a. The structures of free LIR-1 (ref. 11) and LIR-2 (ref. 17) are superimposed on the bound LIR-1 structure to show movement of the loop of residues 76 -84 (mostly disordered in the bound LIR-1 structure (see Methods). The side chains of LIR-1 Asp80 (which have been linked to the binding of LIR-1 UL18; ref. 11) and its counterpart in LIR-2, Arg80, are shown as ball-and-stick representation.

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 code is shown on the right.
