NAMPT 蛋白, Mouse

NAMPT protein has dual functions of cytokine and adipokine. Due to limited ATP activation, its secreted form lacks enzymatic activity. It catalyzes the condensation of nicotinamide and 5-phosphoribosyl-1-pyrophosphate to produce nicotinamide mononucleotide, which is critical for NAD biosynthesis. NAMPT Protein, Mouse is the recombinant mouse-derived NAMPT protein, expressed by E. coli , with tag free. The total length of NAMPT Protein, Mouse is 491 a.a., with molecular weight of 56 kDa.

NAMPT 蛋白具有双重功能，既可作为具有免疫调节特性的细胞因子，又可作为具有抗糖尿病特性的脂肪因子。有趣的是，其分泌形式缺乏酶活性，部分原因是由于其水平较低，细胞外空间和血浆中 ATP 的激活有限。从功能上来说，NAMPT 催化烟酰胺与 5-磷酸核糖基-1-焦磷酸的缩合，产生烟酰胺单核苷酸——NAD 生物合成中至关重要的中间体。NAMPT 作为哺乳动物 NAD 生物合成途径中的限速成分，在调节生物钟功能中发挥着关键作用。其 NAMPT 依赖性振荡产生 NAD，通过从 NAD 依赖性 SIRT1 介导的抑制中释放核心时钟成分 CLOCK-BMAL1 异二聚体，控制时钟靶基因表达的振荡。
