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.
Describe phosphorylation relay in signaling
Introduction:- Signalling is a process through which information are passed or relayed to the cell from outside environment. It involves the use of ligand and receptor molecules. Ligand binds to the receptor present on the cell surface or inside of the cell ( intracellular receptor) and triggers the changes or modifications in the receptor complex that further leads to downward relaying of the signal through a cascade of protein molecules. And finally the expression of a particular gene takes place in response to the signal provided by ligand.
