Rabbit anti-Human KIR3DL2 Polyclonal Antibody

Uniprot Id

P43630

Target Species

Human

Target Name

KIR3DL2

Target Full Name

Killer cell immunoglobulin-like receptor 3DL2

Target Function

Receptor on natural killer (NK) cells and T cells for MHC class I molecules. Upon binding of peptide-free HLA-F open conformer, negatively regulates NK and T cell effector functions. Acts as a receptor on astrocytes for HLA-F. Through interaction with HLA-F, may protect motor neurons from astrocyte-induced toxicity.

Target Subcellular Location

Cell membrane; Single-pass type I membrane protein.

Target Protein Families

Immunoglobulin superfamily

Target Tissue Specificity

Expressed in astrocytes.

Target Synonyms

KIR3DL2; CD158K; NKAT4; Killer cell immunoglobulin-like receptor 3DL2; CD158 antigen-like family member K; MHC class I NK cell receptor; Natural killer-associated transcript 4; NKAT-4; p70 natural killer cell receptor clone CL-5; p70 NK receptor CL-5; CD antigen CD158k

Target Background

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. This gene is one of the "framework" loci that is present on all haplotypes. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.
