分子别名(Synonym)
LILRA4,CD85g,ILT7,ILT-7
表达区间及表达系统(Source)
Human LILRA4 Protein, His Tag (LI4-H52H5) is expressed from human 293 cells (HEK293). It contains AA Glu 24 - Asn 446 (Accession # P59901-1).
Predicted N-terminus: Glu 24
蛋白结构(Molecular Characterization)

This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 48.5 kDa. The protein migrates as 60-66 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
内毒素(Endotoxin)
Less than 1.0 EU per μg by the LAL method / rFC method.
纯度(Purity)
>90% as determined by SDS-PAGE.
制剂(Formulation)
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景介绍
白细胞免疫球蛋白样受体A亚族成员4(LILRA4/ILT7/CD85g)是浆细胞样树突细胞(pDC)的特异性标志物。这类细胞被证实是自身免疫疾病中异常升高的I型干扰素(IFNα)的主要来源。目前正探索通过靶向LILRA4的治疗性抗体促进清除IFNα分泌型pDC,作为缓解自身免疫疾病症状的新策略。该免疫球蛋白样蛋白优先表达于人浆细胞样树突细胞表面,通过与骨髓基质细胞抗原2(BST2)相互作用,调控pDC经Toll样受体(TLR)介导的抗病毒感染应答,并可能参与pDC-肿瘤相互作用的调控。pDCs过量产生的IFNα正是驱动自身免疫疾病症状的关键因子。
