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.
Cells have thousands of different proteins, each with a specific function. Even so, all proteins are polymers constructed from a set of 20 amino acid monomers linked end-to-end, up to thousands of amino acids long, each in a unique 3-D shape.There are 20 amino acid monomers: Each has the overall structure shown at right. 1.A central Carbon (C) 2. An amino group (NH 3) 3.ven so, all proteins are polymers constructed from a set of 20 amino acid monomers linked end-to-end, up to thousands of amino acids long, each in a unique 3-D shape.
