Is PFK-1 activity associated with glycolysis?
Indeed, PFK-1 activity has been correlated with changes in cellular metabolism and physiology. It is increased in response to proliferation signals and is correlated with elevated glycolysis in proliferating cells ( Yalcin et al. 2009b ).Why is PFK-1 activity elevated in oncogenes?
Accordingly, elevated PFK-1 activity is also characteristic of cancer cells and is induced in response to oncogenes or following HIF1α activation ( Moreno-Sanchez et al. 2007; Yalcin et al. 2009b ). Because PFK-1 functions as the gatekeeper to glycolysis, its activity is tightly regulated.What is the difference between Tigar and PFK-1?
What is the difference between Tigar and PFK-1?PFKFB is a bifunctional enzyme where the kinase and bisphosphatase active sites are found in tandem. TIGAR displays partial similarity and possesses only the bisphosphatase active site. PPP, Pentose phosphate pathway. PFK-1 is encoded by three genes: PFK-M (muscle), PFK-L (liver), and PFK-P (plateletes), each encoding a different isoform.
What is the homology of the pfk1p and pfk2p amino acids?
What is the homology of the pfk1p and pfk2p amino acids?The amino acid sequences of Pfk1p and Pfk2p exhibit 20% homology between the N- and the C-terminal halves for each subunit and 55% homology between the two subunits overall.
