Ketohexokinase; Hepatic Fructokinase; Fructokinase; Testicular Tissue Protein Li 102; Ketohexokinase (Fructokinase); EC 2.7.1.3

This gene encodes ketohexokinase that catalyzes conversion of fructose to fructose-1-phosphate. The product of this gene is the first enzyme with a specialized pathway that catabolizes dietary fructose. Alternatively spliced transcript variants encoding different isoforms have been identified.
