Specifications for CD158b2 (KIR2DL3) Antibody, anti-human, REAfinity™


Clone REA147 recognizes CD158b2, a killer cell immunoglobulin-like inhibitory receptor (KIR). Expressed by natural killer (NK) cells and a subset of T cells, KIR family of receptors are transmembrane glycoproteins and interact with MHC class I molecules. This interaction allows the KIR receptors to modulate the killing function of cells bearing them. The KIR proteins are categorized by the number of extracellular immunoglobulin domains (2D or 3D) and by the length (long (L) or short (S)) of the cytoplasmic domain. KIR proteins with the long cytoplasmic domain, such as CD158b2, transduce inhibitory signals via an immune tyrosine-based inhibitory motif (ITIM).
Additional information: Clone REA147 displays negligible binding to Fc receptors.
