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.
There are approximately twenty different amino acids that naturally occur in proteins although there are more than 100 amino acids that occur in nature (mostly in plants). All amino acids have a basic structure that consists of carbon, hydrogen, oxygen, and nitrogen atoms. This is the framework of the amino acid that makes up the protein. Protein molecules are important in cells because they play the role of enzymes and help to catalyze necessary reactions for living organisms as well as help to make up the structure of various cells. Proteins are found in all living organisms. In the early 19th century, the importance of proteins was discovered. Proteins are organ-specific meaning that in an organism, muscle proteins will differ between organs, such as the brain and the liver.
