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.
The set of twenty amino acids commonly found in biological proteins is directly responsible for the diversity of protein structures in living cells. Each protein differs in several aspects that determine structure and, therefore, function. A protein may be composed of one or more polypeptide strands.
