细胞周期蛋白和细胞周期蛋白依赖性激酶有什么区别|比较类似术语之间的差异

这关键区别between cyclins and cyclin dependent kinases是细胞周期蛋白是在细胞周期中没有酶促功能的调节蛋白，而细胞周期蛋白依赖性激酶是在细胞周期中具有酶促功能的催化蛋白。

细胞周期是在细胞中发生的非常重要的事件。这是一系列事件，导致细胞分为两个子细胞。真核细胞周期由四个不同的阶段组成：G1, S, G2和M. G1，S和G2统称为相间。In G1, the cell continues to grow.基因复制takes place in the S phase. In the G2 phase, cells will continue to grow further. Finally, in the M phase,细胞分裂proceeds. Moreover, two regulatory molecules known as cyclins and cyclin-dependent kinases participate in the progression of the cell through the cell cycle. Therefore, cyclins and cyclin dependent kinases are two key classes of proteins that participate in cell cycle regulation.

什么是细胞周期蛋白？

细胞周期蛋白是参与细胞周期的调节蛋白的关键类别。它们没有酶促功能。在所有真核物种中，编码细胞周期蛋白的许多基因都是保守的。H. L Hartwell，R.T Hunt和P.M护士因发现细胞周期蛋白和细胞周期蛋白依赖性激酶而在2001年获得诺贝尔奖。然而，在研究海胆细胞周期时，1982年通过R. Timothy Hunt发现了细胞周期蛋白。

它不具有催化功能。博时nd to cyclin dependent kinases, it forms a complex called maturation promoting factor. This complex activates other proteins through phosphorylation. These phosphorylated proteins are responsible for specific events that occur during the cell cycle, such as microtubule formation and chromatin remodelling. All these events help a cell to progress through the cell cycle. Based on the behaviour of the cell cycle, the cyclins can be divided into four classes: G1 cyclins, G1/S cyclins, S cyclins and M cyclins.

什么是依赖细胞周期蛋白的激酶？

Cyclin dependent kinases are a class of catalytic protein kinases that play an important role in the cell cycle. They are also involved in regulating transcription, mRNA processing, and the differentiation of nerve cells. These proteins are present in all eukaryotes. Their function is evolutionary conserved. Cyclin dependent kinases are small proteins. Their molecular weight ranges from 34 kDa to 40 kDa. They are normally inactive without cyclins.

图02：细胞周期蛋白依赖性激酶

细胞周期蛋白依赖性激酶与称为细胞周期蛋白的调节蛋白结合。没有细胞周期蛋白，细胞周期蛋白依赖性激酶的活性很小。细胞周期蛋白依赖性激酶复合物称为成熟促进因子。该复合物对于细胞在整个细胞周期中的发展非常重要。此外，细胞周期蛋白依赖性激酶磷酸化其丝氨酸和苏氨酸的底物。因此，它们也被称为丝氨酸 - 苏氨酸激酶。此外，细胞周期蛋白依赖性激酶在细胞中组成型表达。

细胞周期蛋白和细胞周期蛋白依赖性激酶有什么区别？

细胞周期蛋白是参与细胞周期中没有酶促功能的调节蛋白，而细胞周期蛋白依赖性激酶是参与细胞周期中具有酶促功能的催化蛋白。因此，这是细胞周期蛋白和细胞周期蛋白依赖性激酶之间的关键差异。此外，细胞周期蛋白在细胞周期的特定阶段表达，响应各种分子信号。另一方面，在整个细胞周期中，细胞周期蛋白依赖性激酶在组成型表达。
