Proteomics South Africa is entering an exciting new era. While genomics has captured global headlines, proteomics the large-scale study of proteins expressed in cells, tissues and biological fluids is increasingly recognised as the scientific discipline closest to the actual mechanisms of disease.
Proteins are the functional molecules that drive nearly every biological process. They regulate immune responses, catalyse chemical reactions, transport molecules and determine how cells respond to infection, stress and treatment.
In South Africa, where HIV, tuberculosis (TB), cancer and metabolic disorders place a significant burden on public health, understanding disease at the protein level is essential. Proteomics enables researchers to identify biomarkers, uncover therapeutic targets and gain a deeper understanding of disease biology.
CPGR is helping lead this effort through its dedicated proteomics and metabolomics hub, D-CYPHR.
What Is Proteomics?
Proteomics is the comprehensive study of all proteins produced by a cell, tissue or organism under specific conditions.
Unlike the genome, which remains relatively stable, the proteome is highly dynamic. Protein expression changes in response to:
- Disease
- Drug treatment
- Diet and nutrition
- Environmental exposures
- Physiological stress
This makes proteomics uniquely valuable for capturing the real-time biological state of a system.
How Proteomics Works
Modern proteomics relies primarily on mass spectrometry (MS).
In a typical workflow:
- Proteins are extracted from a sample.
- Proteins are digested into peptides.
- Peptides are separated by liquid chromatography.
- The mass spectrometer identifies and quantifies peptides.
- Bioinformatics tools reconstruct protein identities and abundances.
Using liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS), researchers can measure thousands of proteins from a single sample.
Why Proteomics Matters
Proteomics reveals biological information that genomics alone cannot, including:
- Post-translational modifications
- Protein-protein interactions
- Cellular signalling states
- Functional pathway activity
These insights are essential for biomarker discovery and precision medicine.
Why Proteomics South Africa Is a Research Priority for Healthcare
South Africa faces a unique and complex disease landscape.
The country carries one of the world’s highest burdens of HIV and tuberculosis, while also experiencing rising rates of:
- Cancer
- Type 2 diabetes
- Obesity
- Cardiovascular disease
- Autoimmune disorders
Proteomics South Africa is a research priority because protein-level changes often occur before clinical symptoms appear. Detecting these changes can lead to:
- Earlier diagnosis
- Improved prognosis
- Better treatment monitoring
- New therapeutic targets
Addressing the African Data Gap
African populations remain significantly underrepresented in global proteomics databases.
Generating proteomics data in South Africa is therefore critical for:
- Building population-relevant reference datasets
- Improving biomarker accuracy
- Ensuring equitable precision medicine
- Increasing Africa’s contribution to global biomedical research
