Product Background

KIR2DL3 (2DL3, formerly NKAT2, designated CD158b2) is a 341 amino acid (aa) type I transmembrane glycoprotein that belongs to the human killer cell Ig‑like receptor (KIR) family of molecules. KIRs are expressed on human CD56dim NK cells and T cell subsets, and regulate effector functions in the innate immune system.KIR2DL3 is a receptor on natural killer (NK) cells for HLA-C alleles (HLA-Cw1, HLA-Cw3 and HLA-Cw7). Inhibits the activity of NK cells thus preventing cell lysis.
