GAPDHS
Glyceraldehyde-3-Phosphate Dehydrogenase (GAPDH): A Multifaceted Enzyme with Diverse Roles
Description
Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is a ubiquitous enzyme found in all living organisms. It plays a crucial role in the process of glycolysis, which converts glucose into pyruvate, providing energy for cellular activities. GAPDH catalyzes the sixth step of glycolysis, where it oxidizes glyceraldehyde-3-phosphate to produce 1,3-bisphosphoglycerate.
Associated Diseases
While GAPDH is essential for normal cellular function, its dysregulation has been linked to several diseases:
- Neurodegenerative Diseases: GAPDH deficiency or mutations have been associated with Alzheimer's disease, Parkinson's disease, and Huntington's disease.
- Cancer: Overexpression of GAPDH has been observed in various types of cancer, including breast cancer, lung cancer, and colon cancer.
- Diabetes: GAPDH has been implicated in insulin resistance and the development of type 2 diabetes.
- Inflammatory Diseases: GAPDH can act as a pro-inflammatory mediator, contributing to conditions like rheumatoid arthritis and inflammatory bowel disease.
Did you Know ?
GAPDH is one of the most abundant proteins in the human body, accounting for up to 4% of total cellular protein content. This high abundance reflects its vital role in energy metabolism and its involvement in multiple cellular processes.
