PE/Cyanine7 anti-human CD158h (KIR2DS1) Antibody, CD158h, S22019F,BioLegend,335009

CD158 molecules, also known as KIRs (killer cell immunoglobulin-like receptors), are a family of transmembrane proteins with either two (KIR2D) or three (KIR3D) Ig-like extracellular domains. Some KIRs with long cytoplasmic domains contain ITIMs and possess inhibitory functions and others with short cytoplasmic region lack ITIMs and have activation functions. Fifteen polymorphic KIR genes have been reported in humans. CD158h is a 50 kD, single-pass glycoprotein with two extracellular Ig domains that contains a short cytoplasmic tail and does not contain an intracellular ITIM domain. It is expressed primarily on a subset of NK cells and a subset of T cells. KIR2DS1 is reported to bind certain HLA-C antigens on target cells (HLA-C*02, HLA-C*04, HLAC*06, for example).
