Mouse TIM-3 / HAVCR2 Protein, His Tag
分子别名(Synonym)
HAVCR2,TIM3,TIMD3,FLJ14428,KIM3
表达区间及表达系统(Source)
Mouse TIM-3, His Tag (TI3-M52H1) is expressed from human 293 cells (HEK293). It contains AA Arg 20 - Arg 191 (Accession # AAL65156.1).
Predicted N-terminus: Arg 20
蛋白结构(Molecular Characterization)

This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 21.0 kDa. The protein migrates as 33-47 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.
纯度(Purity)
>95% as determined by SDS-PAGE.
制剂(Formulation)
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

背景(Background)
甲型肝炎病毒细胞受体2也称为HAVCR2、FLJ14428、KIM3、TIM3、TIMD3,是TIM家族免疫调节分子的成员,具有一个Ig样V型结构域和一个富含Ser/Thr的粘蛋白柄。CD4阳性T辅助淋巴细胞根据其细胞因子分泌模式可分为1型(Th1)和2型(Th2)。Th1细胞及其相关细胞因子参与细胞介导的对细胞内病原体的免疫和迟发型超敏反应,而Th2细胞参与控制细胞外蠕虫感染和促进特应性和过敏性疾病。这两种细胞也交叉调节另一种细胞的功能。HAVCR2是一种Th1特异性细胞表面蛋白,调节巨噬细胞活化,增强小鼠实验性自身免疫性脑脊髓炎的严重程度。HAVCR2调节巨噬细胞活化。抑制T辅助1型淋巴细胞(Th1)介导的自身和同种异体免疫反应,促进免疫耐受。也可能参与T细胞归巢。HAVCR2-galectin-9通路的失调可能是人类慢性自身免疫性疾病状态的基础,如多发性硬化症。
