We are structural biologists concerned with the organization and dynamics of macromolecular assemblies. The long-term objective of our research is to determine how protein interactions determine subcellular structures. Ribbon diagrams, also known as Richardson Diagrams, are 3D schematic representations of protein structure and are one of the most common methods of protein depiction used today. Proteins are essential parts of organisms and participate in virtually every process within cells.

Proteins are networks dynamically organizing molecules that may consist of hundreds, or even thousands of amino acids. While there are hundreds of thousands of different proteins that exist in nature, they are all made up of different combinations of just 20 amino acids. They play the role of balancing channels to process movement and flow in diffusion. Transport Proteins are carrier proteins which move molecules from one place to another around the body. Storage Proteins store amino acids. Structural Proteins are fibrous and stringy and provide support. Hormonal Proteins are messenger proteins which help to coordinate certain bodily activities. Enzymes are proteins that facilitate biochemical reactions. Contractile Proteins are responsible for movement. Antibodies are specialized proteins involved in defending the body from foreign invaders.
