| 产品介绍 | background: Protein phosphatase 2A (PP2A) is the most abundant phosphatase specific for serine and threonine phosphorylation in mammalian cells. It consists of a common heteromeric core enzyme, which is composed of a catalytic subunit and a constant regulatory subunit, that associates with a variety of regulatory subunits. The constant regulatory subunit alpha (PPP2R1A) serves as a scaffolding molecule to coordinate the assembly of the catalytic subunit and a variable regulatory beta subunit. Function: The PR65 subunit of protein phosphatase 2A serves as a scaffolding molecule to coordinate the assembly of the catalytic subunit and a variable regulatory B subunit. Required for proper chromosome segregation and for centromeric localization of SGOL1 in mitosis. Subunit: Found in a complex with at least ARL2, PPP2CB, PPP2R1A, PPP2R2A, PPP2R5E and TBCD (By similarity). PP2A consists of a common heterodimeric core enzyme, composed of PPP2CA a 36 kDa catalytic subunit (subunit C) and PPP2R1A a 65 kDa constant regulatory subunit (PR65 or subunit A), that associates with a variety of regulatory subunits. Proteins that associate with the core dimer include three families of regulatory subunits B (the R2/B/PR55/B55, R3/B''/PR72/PR130/PR59 and R5/B'/B56 families), the 48 kDa variable regulatory subunit, viral proteins, and cell signaling molecules. Interacts with IPO9. Interacts with TP53 and SGOL1. Interacts with PLA2G16; this interaction might decrease PP2A activity. Subcellular Location: Cytoplasm. Chromosome, centromere. Similarity: Belongs to the phosphatase 2A regulatory subunit A family. Contains 15 HEAT repeats.

文献和实验组是动态的，随着大量刺激的变化而变化，翻译后修饰常用于调节细胞活性。PTM 发生在不同的氨基酸侧链或肽键上，它们通常由酶活性介导。事实上，据估计，5% 的蛋白质组包含 200 多种类型翻译后修饰的酶。这些酶包括激酶、磷酸酶、转移酶和连接酶，它们在氨基酸侧链上添加或移除功能组、蛋白质、脂质或糖；以及蛋白酶，它们切割肽键以移除特定序列或调节亚基。许多蛋白质也可以利用自催化结构域，如自激酶和自蛋白分解结构域进行自我修饰。翻译后修饰可以发生在蛋白质生命周期的任何阶段。例如，许多蛋白质在翻译完成后不久就被修饰

果糖激酶(和丙酮酸激酶)的活性，这不但减慢了糖酵解的速度，还可以通过激活果糖-1，6-二磷酸酶而使糖代谢方向倾向于糖异生。因此，改变某些关键酶的活性是体内代谢调节的一种重要方式。 人体代谢的细胞水平调节，从速度方面来说有两种方式，一种是快速调节，一般在数秒或数分钟内即可发生。这种调节是通过激活或抑制体内原有的酶分子来调节酶促反应速度的，是在温度、pH、作用物和辅酶等因素不变的情况下，通过改变酶分子的构象或对酶分子进行化学修饰来实现酶促反应速度的迅速改变的。另一种是迟缓调节，一般经数小时
