PFKFB3 Antibody #9645
|W||H M R Mk||Endogenous||60||Rabbit|
Reactivity Key: H=Human M=Mouse R=Rat Mk=Monkey
Species cross-reactivity is determined by western blot. Species enclosed in parentheses are predicted to react based on 100% sequence homology.
Specificity / Sensitivity
PFKFB3 Antibody recognizes endogenous levels of total PFKFB3 protein.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gly452 of human PFKFB3 protein. Antibodies are purified by protein A and peptide affinity chromatography.
The bifunctional 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase (PFK-2/FBPase or PFKFB) catalyzes the synthesis and degradation of fructose 2,6-bisphosphate and regulates its steady-state level (1,2). Fructose 2,6-bisphosphate activates phosphofructokinase, a rate-limiting enzyme in glycolysis, by allosteric regulation (1,2). Four different PFKFB isoforms (PFKFB1, PFKFB2, PFKFB3, and PFKFB4) have been identified (1,2). One of them, PFKFB3/iPFK-2, was shown to be inducible by hypoxia leading to increased glycolysis under hypoxic conditions (2). Research studies have shown that PFKFB3/iPFK-2 is also highly expressed in some types of human cancer (3).
