Post-Translational Modifications and Proteomics

This topic focuses on post-translational modifications (PTMs) and their analysis using mass spectrometry-based proteomics, a sophisticated area of study in tertiary-level clinical biochemistry and molecular biology. Zambian university students will learn that PTMs (e.g., phosphorylation, glycosylation, acetylation) are chemical changes to proteins after translation that critically regulate their function, activity, localization, and stability. The topic covers how mass spectrometry, coupled with liquid chromatography, is the primary tool for identifying and quantifying these modifications on a large scale (proteomics). For Zambian college and degree learners, understanding PTMs is essential for grasping cellular signaling, disease mechanisms (like cancer and neurodegenerative disorders), and the discovery of novel drug targets and biomarkers. Mastery of proteomics concepts is increasingly important for examinations and is a highly specialized skill for careers in biomedical research, pharmaceutical sciences, and advanced diagnostic development, enhancing the depth of scientific expertise available within Zambia.
