Molecular Orchestration of Life: The Integrative Role of Post-Translational Modifications in Signal Transduction and Metabolic Reprogramming

Abstract

The PTMs play a paramount role in protein regulation in terms of functionality, shape, and interactions. They are post-synthetic modifications that have crucial functions in signal transduction and metabolic reprogramming, and with their assistance, cells can dynamically respond to the state of the internal and external environment. The current paper will examine the functions of different PTMs such as phosphorylation, acetylation, methylation and ubiquitination and how they affect important proteins, which play a major role in cellular signaling and metabolism. The paper talks about the role of PTMs directing cellular processes in health and disease and specifically cancer as well as the therapeutic value of attacking PTM regulators. The data provided in terms of biochemical assays, mass spectrometry, and cellular assays are given to demonstrate the functional implications of PTMs in signal transduction and metabolic pathways.
