Membrane protein

Membrane proteins are specialized proteins located within or on the surfaces of cell membranes. They play crucial roles in various functions, such as transporting substances in and out of cells, signaling between cells, and maintaining the cell's structure. Think of them as gatekeepers and communicators that help cells interact with their environment. These proteins can be categorized into two main types: integral proteins, which span the membrane, and peripheral proteins, which are attached to the surface. Overall, membrane proteins are essential for the proper functioning of cells and contribute to many biological processes.
