查询词典 proteins

The identified proteins were divided into two following categories: one is regulatory proteins, for example, caffeic acid 3-O-methyltransferas, HSP70, glyoxalase I , actin, and so on. They are involved in protein biosynthesis and processing, cellular structural organization and stress responses. The other is function proteins, for instance, ascorbate peroxidase, cytoplasmic malate dehydrogenase, cytosolic phosphoglycerate kinase, S-adenosyl methionine synthetase, ATP synthase, and so on. They are involved in photosynthesis, photorespiration, redox homeostasis, and metabolisms.

通过分析可以将这些差异蛋白分为两大类：第一类是调节性蛋白，如咖啡酸三氧转甲基酶，热激蛋白70，醛酮变位酶I，肌动蛋白等，它们主要参与蛋白质的合成和加工、胁迫响应、细胞骨架稳定等过程；第二类是功能性蛋白，如抗坏血酸过氧化物酶，细胞质苹果酸脱氢酶，细胞质磷酸甘油酸激酶，S-腺苷蛋氨酸合成酶，ATP合酶等，它们则参与氧化还原平衡、光合作用、光呼吸和各种代谢等过程。

Simultaneously, according to different target proteins, these two mechanisms of PIAS proteins are not absolutely repulsive, which indicates the specificity and complexity of the function of PIAS proteins.

同时，针对不同的靶蛋白，PIAS蛋白的上述两种作用机制并不是完全互相排斥的，这体现了PIAS蛋白功能的特异性和复杂性。

PIAS proteins play roles mainly through two mechanisms: acting as SUMO E3 ligases to promote modifications of some transcriptional factors and cofactors, especially sumoylation, and to regulate their transcriptional activation; acting as structural proteins to offer platforms for protein-protein interactions and to promote the abstraction and recruitment of other regulators in the cellular signal pathway complexes or gene transcriptional complexes, companied by the subnuclear location of target proteins.

PIAS蛋白的调控机制主要有两种：一种是通过其自身所具有的SUMO(small ubiquitin-related modifiers)E3连接酶活性，促进对一些转录因子、转录辅因子的化学修饰，尤其是SUMO化修饰，从而调控它们的转录活性；另一种是作为构架蛋白，为蛋白质之间的相互作用提供平台，促进细胞信号通路复合物或基因转录复合物中其它调节蛋白的去除和募集，并涉及到靶蛋白的亚核定位。

There are some isoforms of PAPs showing inhibitory ability to virus infection in various organs and at different stages of development. Three different species of the protein can be isolated from leaves of pokeweed. Proteins were precipitated with 50-80% ammonium sulfate from leaves in spring, summer and autumn respectively. Proteins were purified on SP cation-exchange then on MQ anion-exchange and finally on MS cation-exchange or on MQ anion-exchange. We found that some new pokeweed antiviral proteins separated from these leaves were different from PAP, PAPII and PAPIII.
