6-phosphofructokinase, liver type is an enzyme that in humans is encoded by the PFKL gene.[1] Phosphofructokinase (PFK) is a tetrameric enzyme that catalyzes a key step in glycolysis, namely the conversion of D-fructose 6-phosphate to D-fructose 1,6-bisphosphate. Separate genes encode a muscle subunit (M) and a liver subunit (L). PFK from muscle is a homotetramer of M subunits, PFK from liver is a homotetramer of L-subunits, while PFK from platelets can be composed of any tetrameric combination of M and L subunits. The protein encoded by this gene represents the L subunit. Two transcript variants encoding different isoforms have been found for this gene.[1]

Model organisms

knockout mouse line, called Pfkltm1a(EUCOMM)Wtsi[6][7] was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists.[8][9][10]

Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.[4][11] Twenty six tests were carried out on mutant mice and three significant abnormalities were observed.[4] Few homozygous mutant embryos were identified during gestation, and none survived until weaning. The remaining tests were carried out on heterozygous mutant adult mice and a hair follicle degeneration phenotype was observed.[4]
