B4GALT1 蛋白, Human (HEK293, Y285L, His)

B4GALT1 Protein, Human (HEK293 His) is responsible for the overcoming multidrug resistance in human leukemia therapy via regulating the activity of the hedgehog signaling pathway^[1][2].

B4GALT1 表达被确定为非转移性透明细胞肾细胞癌模型中生存的独立不良预后因素^[1]。B4GALT1基因在生理过程和疾病发生发展中发挥重要作用。B4GALT1 被证明负责许多糖蛋白中复合型 N 连接寡糖的合成以及糖脂的碳水化合物部分^[2]。B4GALT1 是维持肺癌干细胞干性的新候选者^[3]。

Measured by its ability to transfer N-Acetyl-D-galactosamine from UDP-GalNAc to N-Acetyl-D-glucosamine that incubate at 37℃ for 20 min. The specific activity is 415.10-526.68 pmol/min/μg.
