KIR2DL4 Antibody (C-term) Blocking Peptide

Synthetic peptide

Product Information
Primary Accession Q99706
Clone Names 90805055
Additional Information
Gene ID 3805
Other Names Killer cell immunoglobulin-like receptor 2DL4, CD158 antigen-like family member D, G9P, Killer cell inhibitory receptor 103AS, KIR-103AS, MHC class I NK cell receptor KIR103AS, CD158d, KIR2DL4, CD158D, KIR103AS
Target/Specificity The synthetic peptide sequence used to generate the antibody AP9042b was selected from the C-term region of human KIR2DL4. A 10 to 100 fold molar excess to antibody is recommended. Precise conditions should be optimized for a particular assay.
Format Synthetic peptide was lyophilized with 100% acetonitrile and is supplied as a powder. Reconstitute with 0.1 ml DI water for a final concentration of 1 mg/ml.
StorageMaintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C.
PrecautionsThis product is for research use only. Not for use in diagnostic or therapeutic procedures.
Protein Information
Name KI2L4
Function Receptor for non-classical major histocompatibility class Ib HLA-G molecules. Recognizes HLA-G in complex with B2M/beta-2 microglobulin and a nonamer self-peptide (peptide-bound HLA-G-B2M). In decidual NK cells, binds peptide-bound HLA-G-B2M complex and triggers NK cell senescence-associated secretory phenotype as a molecular switch to promote vascular remodeling and fetal growth in early pregnancy (PubMed:23184984, PubMed:29262349, PubMed:16366734). May play a role in balancing tolerance and antiviral-immunity at maternal-fetal interface by keeping in check the effector functions of NK, CD8+ T cells and B cells (PubMed:10190900, PubMed:16366734). Upon interaction with peptide-bound HLA-G-B2M, initiates signaling from the endosomal compartment leading to downstream activation of PRKDC-XRCC5 and AKT1, and ultimately triggering NF-kappa-B-dependent proinflammatory response (PubMed:20179272).
Cellular Location Cell membrane; Single-pass type I membrane protein. Early endosome membrane
Tissue Location Expressed in decidual NK cells and innate lymphoid cell type I (ILC1) (PubMed:29262349). Expressed in a subset of peripheral NK cells (PubMed:19304799).

KIR2DL4 is killer cell immunoglobulin-like receptors (KIRs) which 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).
