Regulation of Cellular Pathways: Role of Ptms

Post-translational modifications (PTMs) are chemical changes to proteins after they are made by the cell. These modifications serve as “switches” to turn various cellular processes on and off, and regulate the activity of proteins involved in many cellular pathways. PTMs help cells respond to external cues and influence cell activity and metabolism. They are involved in a wide range of cellular processes, such as growth, differentiation, energy production, and immunity. PTMs can also play a role in disease processes, such as cancer and inflammatory disorders, making them a valuable target for therapeutic strategies. Understanding the role of PTMs in regulating cellular pathways is essential to advancing our understanding of normal and abnormal biological processes.
