Structure of the human NK cell triggering receptor NKp46 ectodomain.

NKp46, a natural killer (NK) cell-specific receptor, has been recently identified as one of the triggering receptors involved in NK cell activation mediated by non-HLA class I ligands. The structure of the NKp46 extracellular receptor region, here reported, consists of two Ig-like domains assembled similarly to leukocyte immunoglobulin-like receptors (LIRs… (More)
