Human CD117 / c-kit Protein, Fc Tag (MALS verified)
分子别名(Synonym)
CD117, SCFR, c-Kit, KIT
表达区间及表达系统(Source)
Human CD117, Fc Tag (CD7-H5255) is expressed from human 293 cells (HEK293). It contains AA Gln 26 - Thr 516 (Accession # P10721-2).
Predicted N-terminus: Gln 26
蛋白结构(Molecular Characterization)

This protein carries a human IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 81.9 kDa. The protein migrates as 95-120 kDa when calibrated against Star Ribbon Pre-stained Protein Marker 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)
>95% as determined by SDS-PAGE.
制剂(Formulation)
Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5 with trehalose as protectant.

背景介绍
肥大/干细胞生长因子受体Kit(c-Kit)属于蛋白激酶超家族、酪氨酸蛋白激酶家族及CSF-1/PDGF受体亚家族,亦被称为白斑特质蛋白(PBT)、p145 c-kit、酪氨酸蛋白激酶Kit或CD117。该受体包含五个Ig样C2型结构域及一个蛋白激酶结构域。CD117作为细胞因子KITLG/SCF的细胞表面受体,在细胞存活与增殖、造血作用、干细胞维持、配子发生、肥大细胞发育迁移与功能以及黑色素生成中起关键作用。当与KITLG/SCF结合后,CD117可激活多条信号通路。此外,活化后的KIT能促进蛋白磷酸酶PTPN6/SHP-1、PTPRU以及转录因子STAT1、STAT3、STAT5A和STAT5B的磷酸化。
