Swiss-port # Q99706 Human Killer cell immunoglobulin-like receptor 2DL4 |
|---|---|
| 基因名称 | KIR2DL4 |
| 全名 | killer cell immunoglobulin-like receptor, two domains, long cytoplasmic tail, 4 |
| 背景介绍 | CD158d / KIR2DL4 is a KIR family member that shares structural features with both activating and inhibitory receptors and may mediate different functions under different circumstances. It contains cytoplasmic ITIM, suggesting inhibitory function, but also transmembrane domain similar to those of activating KIRs. It has been reported that CD158d serves as an inhibitory receptor for peripheral and uterine NK cells, but its ligation with soluble mAbs (unlike immobilized mAbs) results in activation of IFN-γ secretion. CD158d also binds both membrane form and soluble form of its ligand HLA-G. |
| 生物功能 | Receptor on natural killer (NK) cells for HLA-C alleles. Inhibits the activity of NK cells thus preventing cell lysis. [UniProt] |
| 研究领域 | Immune System antibody |
| 预测分子量 | 41 kDa |
