A Microtubules will rapidly disassemble in response to a drop in the ATP concentration. B G-actin monomers and alpha-tubulin/beta-tubulin dimers assemble into filaments in their ATP-bound and GTP-bound forms, respectively. C Microtubules are stabilized by microtubule-binding proteins, such as Tau. D Actin-binding proteins allow F-actin to assemble in cells in many different ways. E Hydrolysis of ATP and GTP changes the conformation of the monomers once they are incorporated into actin filaments and microtubules, respectively
Proteins
We generally tend to think of proteins only from a dietary lens, as a component of what we eat. However, they are among the most important and abundant organic macromolecules in the human body, with diverse structures and functions. Every cell contains thousands and thousands of proteins, each with specific functions. Some help in the formation of cellular membrane or walls, some help the cell to move, others act as messages or signals and flow seamlessly from one cell to another, carrying information.
Protein Expression
The method by which living organisms synthesize proteins and further modify and regulate them is called protein expression. Protein expression plays a significant role in several types of research and is highly utilized in molecular biology, biochemistry, and protein research laboratories.
