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.
What are HU and H-NS (Histone-like Nucleoid Structuring) proteins ?
Chromatin is a substance found within chromosomes that is made up of DNA and protein. The DNA carries the genetic information for the cell. Histones are the primary proteins in chromatin, and they help bundle the DNA into a compact shape that fits in the cell nucleus. Chromatin structural changes are linked to DNA replication and gene expression. There are different kinds of histones proteins that are associated with chromatin to make chromosome, a compact structure.
