Amyloid β (Aβ) precursor protein (APP) is a 100-140 kDa transmembrane glycoprotein that exists as several isoforms (1). The amino acid sequence of APP contains the amyloid domain, which can be released by a two-step proteolytic cleavage (1). The extracellular deposition and accumulation of the released Aβ fragments form the main components of amyloid plaques in Alzheimer's disease (AD) (1). APP can be phosphorylated at several sites, which may affect the proteolytic processing and secretion of this protein (2-5). Phosphorylation at Thr668 (a position corresponding to the APP695 isoform) by cyclin-dependent kinase is cell-cycle dependent and peaks during G2/M phase (4). APP phosphorylated at Thr668 exists in adult rat brain and correlates with cultured neuronal differentiation (5,6).

β淀粉样蛋白(Amyloid β,Aβ)前体蛋白(Amyloid β precursor protein, APP)是分子量为100-140 kDa的跨膜糖蛋白,它拥有几个亚型(1)。APP的氨基酸序列中所包含的淀粉样蛋白域(A-β),能够通过两步蛋白裂解反应被释放出来(1)。释出的A-β片段在细胞外沉积积累,形成了阿尔茨海默病(Alzheimer's disease,AD)中淀粉样斑块的主要组成部分(1)。APP存在多个能够被磷酸化的位点,这些位点影响着蛋白本身的裂解和分泌过程(2-5)。细胞周期蛋白依赖性激酶介导的Thr688(对应于APP695亚型)磷酸化是细胞周期依赖的,在G2/M期达到峰值(4)。APP的Thr668磷酸化形式存在于成年大鼠大脑和相应的培养神经细胞及其分化细胞中(5,6)。
