These receptors all contain a cytoplasmic immunoreceptor tyrosine-based inhibitory motif (ITIM), have an inhibitory function and are type I membrane proteins. When they bind to MHC (or other ligands) and ITIM is tyrosine phosphorylated, protein-tyrosine phosphatases are recruited and an inhibitory signal cascade triggered. ILT-4, also designated LIR-2, MIR-10 or CD85D antigen, competes with CD8A for binding to class I MHC antigens.
Function:
Receptor for class I MHC antigens. Recognizes a broad spectrum of HLA-A, HLA-B, HLA-C and HLA-G alleles. Involved in the down-regulation of the immune response and the development of tolerance. Competes with CD8A for binding to class I MHC antigens. Inhibits FCGR1A-mediated phosphorylation of cellular proteins and mobilization of intracellular calcium ions.
Subcellular Location:
Membrane.
Tissue Specificity:
Expressed on monocytes and B-cells, and at lower levels on dendritic cells. Detected at low levels in natural killer (NK) cells.
Post-translational modifications:
Phosphorylated on tyrosine residues. Dephosphorylated by PTPN6.
Similarity:
Contains 4 Ig-like C2-type (immunoglobulin-like) domains.

文献和实验抗体的概念 抗体（antibody, Ab），也叫免疫球蛋白（immunoglobulin, Ig），是血液和组织液中的一类糖蛋白，由B细胞接受抗原刺激后增殖分化成的浆细胞产生，能与相应抗原特异性地结合，是介导体液免疫的重要效应分子。1968年和1972年世界卫生组织和国际免疫学联合会的专门委员会先后决定，将具有抗体活性或化学结构与抗体相似的球蛋白统称为免疫球蛋白。后来研究证实，Ig和Ab在结构及功能上完全一致，因此可认为二者的概念等同。Ig可分为分泌型和跨模型，前者主要存在于血液和组织液中

，为了实现基因靶向转移，可以构建一种可溶性分子复合物载体系统，它包含两个功能区：DNA结合区，常用L―多聚赖氨酸、脂质体等，它们通过静电方式结合DNA或将DNA包裹；配体或抗体区，它们通过识别肿瘤细胞表面受体或抗原，选择性地内化进入肿瘤细胞。Uherek等将酵母转录因子Gal4的DNA结合结构域与白喉毒素转膜结构域、抗ErbB2抗体片段依次连接，构建了一种新的融合蛋白载体，它可与质粒形成复合物，用L―多聚赖氨酸处理后，可特异性地将外源基因导人ErbB2阳性的肿瘤细胞中。
