PFKP (Phosphofructokinase, Platelet): PFKP is a key enzyme in the glycolytic pathway that regulates the rate of glucose metabolism. It catalyzes the conversion of fructose-6-phosphate to fructose-1,6-bisphosphate. Proper regulation of PFKP is essential for cellular energy production, and its dysregulation has been studied in cancer, where altered glucose metabolism is commonly observed.
