| Form | Lyophilized To keep the original salt concentration, we recommend reconstituting to the original concentration prior to lyophilization (see Concentration) in ddH2O. If a lower concentration is required, dilute in PBS, pH 7.4. If a higher concentration is required, the product can be reconstituted directly in PBS, pH 7.4, though please note that this will change the overall salt concentration. The stock concentration should be between 0.1-1.0 mg/ml. Do not vortex. |

Descripción
Killer cell immunoglobulin-like receptors (KIRs) are a family of proteins primarily expressed on the surface of natural killer (NK) cells and some T-cell subsets. KIR2DL2, a member of this family, plays an essential role in regulating NK cell function and contributes to immune surveillance and self-tolerance mechanisms. KIR2DL2 is an inhibitory receptor that recognizes specific human leukocyte antigen (HLA) class I molecules on target cells, allowing NK cells to modulate their activity in response to changes in HLA expression, which often occur in cells affected by infection, cancer, or other pathological states. KIR2DL2’s primary role is to suppress NK cell activity upon binding to its specific HLA ligand, which reduces the likelihood of NK cell-mediated destruction of healthy cells displaying self-HLA markers. The genes encoding KIR proteins, including KIR2DL2, are located on chromosome 19q13.4 within the leukocyte receptor complex (LRC). KIR genes are highly polymorphic, with significant inter-individual variability in gene content and sequence. This variability contributes to an individual’s unique immune response capacity, as well as to population-level diversity in immune defense. The primary ligand for KIR2DL2 is HLA-C, specifically the HLA-C1 epitope (characterized by the presence of asparagine at position 80), which is distinct from the HLA-C2 epitope (lysine at position 80) recognized by other KIR molecules like KIR2DL1.

Killer cell immunoglobulin-like receptors (KIRs) are transmembrane glycoproteins expressed by natural killer cells and subsets of T cells. The KIR genes are polymorphic and highly homologous and they are found in a cluster on chromosome 19q13.4 within the 1 Mb leukocyte receptor complex (LRC). The gene content of the KIR gene cluster varies among haplotypes, although several 'framework' genes are found in all haplotypes (KIR3DL3, KIR3DP1, KIR3DL4, KIR3DL2). The KIR proteins are classified by the number of extracellular immunoglobulin domains (2D or 3D) and by whether they have a long (L) or short (S) cytoplasmic domain. KIR proteins with the long cytoplasmic domain transduce inhibitory signals upon ligand binding via an immune tyrosine-based inhibitory motif (ITIM), while KIR proteins with the short cytoplasmic domain lack the ITIM motif and instead associate with the TYRO protein tyrosine kinase binding protein to transduce activating signals. The ligands for several KIR proteins are subsets of HLA class I molecules; thus, KIR proteins are thought to play an important role in regulation of the immune response.
