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.
Explain Activator protein families?
DNA and RNA are the genetic elements present in almost all cells. DNA encodes for proteins through genes. Gene expression is carried out through transcription process by RNA.
A transcriptional activator is a protein family which induces the transcription of a gene or gene sets. Mostly activators proteins bind to the DNA with enhancers and promoter-proximal elements. The DNA site bound by the activator is referred to as an "activator site". The part of the activator that makes protein–protein interactions with the general transcription machinery is referred to as an activating region. The part of the general transcription machinery that makes protein–protein interactions with the activator is referred to as an activation target.
