Biochem/physiol Actions
碱性磷酸酶 (Alkaline phosphatase)，来源于大肠杆菌，是一种主要存在于周质空间的二聚体、非糖基化蛋白质。已知存在三种亚型。这种酶需要锌，并被镁激活。大肠杆菌含皂碱磷酸酶对磷酸酯具有广泛的特异性。
碱性磷酸酶是研究磷酸酯酶的模型酶。用于各种生化方法和酶联免疫吸附试验 (ELISA)。

TAR DNA-binding protein (TDP-43) has been recently described as a major pathological protein in both frontotemporal dementia with ubiquitin-positive inclusions (FTLD-U) and amyotrophic lateral sclerosis. However, little is known about the relative abundance and distribution of different pathological TDP-43 species
