分子別名(Synonym)
CD73,NT5E,5'-Nucleotidase,5'-NT,NT5,NTE
表達區(qū)間及表達系統(tǒng)(Source)
Mouse CD73, His Tag (CD3-M52H9) is expressed from human 293 cells (HEK293). It contains AA Trp 29 - Ser 551 (Accession # Q61503-1).
Predicted N-terminus: Trp 29
蛋白結構(Molecular Characterization)

This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 59.9 kDa. The protein migrates as 66 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
內毒素(Endotoxin)
Less than 1.0 EU per μg by the LAL method.
純度(Purity)
>90% as determined by SDS-PAGE.
制劑(Formulation)
Lyophilized from 0.22 μm filtered solution in 20 mM Tris, 120 mM NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

背景(Background)
5'-核苷酸酶(5'-NT),也稱為胞外-5'-核苷酸酶或CD73(分化簇73),是由NT5E基因編碼的酶。CD73通常用于將AMP轉化為腺苷。外切5-三核苷酸酶(5-核糖核苷酸磷酸水解酶)在中性pH下催化嘌呤5-三核苷酸轉化為核苷,優(yōu)選的底物是AMP。其他形式的5-三聚核苷酸酶存在于細胞質和溶酶體中,可以通過其底物親和力、對二價鎂離子的需求、ATP的激活和無機磷酸鹽的抑制與胞外NPT5區(qū)分開來。罕見的等位基因變異與成人發(fā)病的關節(jié)和動脈鈣化綜合征(CALJA)有關,該綜合征影響髂、股和脛動脈,減少腿部和手腳關節(jié)的循環(huán),導致疼痛。
