WD40 domain, found in a number of eukaryotic proteins that cover a wide variety of functions including adaptor/regulatory modules in signal transduction, pre-mRNA processing and cytoskeleton assembly; typically contains a GH dipeptide 11-24 residues from its N-terminus and the WD dipeptide at its C-terminus and is 40 residues long, hence the name WD40; between GH and WD lies a conserved core; serves as a stable propeller-like platform to which proteins can bind either stably or reversibly; forms a propeller-like structure with several blades where each blade is composed of a four-stranded anti-parallel b-sheet; instances with few detectable copies are hypothesized to form larger structures by dimerization; each WD40 sequence repeat forms the first three strands of one blade and the last strand in the next blade; the last C-terminal WD40 repeat completes the blade structure of the first WD40 repeat to create the closed ring propeller-structure; residues on the top and bottom surface of the propeller are propos

WD40域，在真核蛋白质的数量发现，涵盖了包括各种功能适配器/信号转导，mRNA前体细胞骨架组装加工和管理模式；通常包含一个从11月24日生长激素肽的N残留端和西部数据肽在其C端和40残留长，因而得名WD40；介于生长激素和WD一个保守的核心，作为一个稳定的螺旋桨式平台，可以绑定的蛋白可以稳定或可逆，形成了一个螺旋桨式与每个刀片是一个四叶片结构组成若干链反平行的β-片；与数份检测实例假设，形成了聚大结构，每个WD40重复序列形成了前三个一个刀片和绞线的最后在未来的刀片链，最后C -末端WD40重复完成了第一WD40重复叶片结构，创造螺旋桨的封闭环结构，对螺旋桨顶部和底部表面残留的建议，配合和其他蛋白质的相互作用/或小配体； 7重复副本，目前这条路。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
