For reconstitution, add sterile, distilled water to achieve a final antibody concentration of 1 mg/mL. Gently shake to solubilize the protein completely. Do not vortex. Reconstituted products should be stored at -80 °.
KIR2DL1 gene encodes a myotubularin-related protein. The encoded protein is a phosphoinositide phosphatase that specifically dephosphorylates phosphatidylinositol 3,5-biphosphate and phosphatidylinositol 3-phosphate. Mutations in this gene are correlated with autosomal dominant centronuclear myopathy. Alternate splicing results in multiple transcript variants. A pseudogene of this gene is found on chromosome 18. KIR2DL2 and KIR2DL3 are genes belonging to the killer cell immunoglobulin-like receptor (KIR) family, located on chromosome 19q13.4. They encode inhibitory receptors expressed primarily on natural killer (NK) cells and a subset of T cells. The proteins produced by these genes play a key role in regulating the immune response through their interaction with human leukocyte antigen (HLA) class I molecules, specifically HLA-C alleles. KIR2DL2 recognizes a broad range of HLA-C alleles with a lysine at position 80 (C1 group), while KIR2DL3 has a higher affinity for the HLA-C1 group. Structurally, these receptors consist of two extracellular immunoglobulin-like domains, a transmembrane region, and a long cytoplasmic tail that contains immunoreceptor tyrosine-based inhibitory motifs (ITIMs). Upon ligand binding, these receptors transmit inhibitory signals to prevent NK cell activation, thereby protecting healthy cells from immune destruction.
