Membrane proteins are proteins that interact with biological membranes. They are one of the common types of protein along with soluble globular proteins, fibrous proteins, and disordered proteins. They are targets of over 50% of all modern medicinal drugs. It is estimated that 20â30% of all genes in most genomes encode membrane proteins.
Some proteins are in the form of channels located in the membrane to allow different biomolecules to pass selectively through the membrane. Thus, a single cell contains thousands of types of proteins and each of them has their own roles and functions to perform inside the cell. That keeps the cell alive and active. However, not all the proteins are expressed at a time but are expressed according to the current need of the cell.
