Human TREM2 Protein, His Tag
分子别名(Synonym)
Triggering receptor expressed on myeloid cells 2,TREM2,TREM-2
表达区间及表达系统(Source)
Human TREM2, His, Tag (TR2-H52H5) is expressed from human 293 cells (HEK293). It contains AA His 19 - Ser 174 (Accession # Q9NZC2-1).
Predicted N-terminus: His 19
蛋白结构(Molecular Characterization)

This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 19.3 kDa. The protein migrates as 28-35 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.
内毒素(Endotoxin)
Less than 1.0 EU per μg by the LAL 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(Background)
TREM2是免疫球蛋白超家族的细胞表面受体。TREM2存在于各种组织巨噬细胞中,如中枢神经系统小胶质细胞、骨破骨细胞、肺泡、腹膜和肠巨噬细胞。TREM2也存在于培养的骨髓来源的巨噬细胞和单核细胞来源的树突状细胞上。一些研究已经确定了TREM2的一种罕见变体,这是阿尔茨海默病(AD)的危险因素,阿尔茨海默病是最常见的迟发性痴呆症。TREM2的细胞外区域包含一个免疫球蛋白超家族结构域,并结合多阴离子配体,如细菌脂多糖(LPS)和磷脂8。配体结合后,TREM2通过衔接子DAP12(也称为TYRO蛋白酪氨酸激酶结合蛋白(TYROBP))传递细胞内信号,DAP12与TREM2的跨膜区相关,并通过其细胞质免疫受体酪氨酸基激活基序(ITAM)招募蛋白酪氨酸激酶SYK。TREM2是小鼠模型和人类肿瘤中肿瘤浸润巨噬细胞的促致瘤标志物,可以靶向抑制肿瘤生长,提高检查点阻断治疗的疗效,同时重塑肿瘤浸润巨噬细胞景观。
