A class of protein molecules is intimately associated with cell membranes. These proteins are embedded within the phospholipid bilayer, spanning all or part of the membrane. As an example, consider a channel protein that allows specific molecules to pass through the membrane, illustrating how such a structure is fundamentally integrated within the membrane’s architecture.
The presence of these embedded proteins is crucial for a cell’s ability to interact with its environment, transport substances, and maintain its internal environment. Historically, the understanding of their structure and function has been pivotal in developing targeted drug therapies and in comprehending the complexities of cellular communication. This deeper understanding has significantly contributed to advancements in biochemistry and molecular biology.
