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 the function for
1.Diacylglycerol (DAG)
2.Inositol Trisphosphate (IP3)
- DAG (diacylglycerol) and IP3 (inositol triphosphate) are produced from PIP2 by phospholipase C. (phosphatidylinositol-4,5-bisphosphate).
- Second messengers provide a direct link between changes in gene expression and signalling molecules like neurotransmitters, cytokines, and growth factors, which are ultimately in charge of the proliferation, differentiation, and maturation of nerve cells.
- Diacylglycerol (DAG) is a crucial lipid that can function as a signalling lipid as well as an intermediary in lipid biosynthesis pathways. Phospholipase C hydrolyzes phosphatidylinositol-4,5-bisphosphate (PIP2) to produce the majority of the signalling DAG, although phosphatidic acid phosphatases (PAPs) can also remove the phosphate head group from phosphatidic acid to produce DAG (PA).
- DAG, a protein kinase C (PKC) activator, can cause the differentiation of monocytes into macrophages.
