== Disease ==
[https://www.uniprot.org/uniprot/KPYR_HUMAN KPYR_HUMAN] Defects in PKLR are the cause of pyruvate kinase hyperactivity (PKHYP) [MIM:[https://omim.org/entry/102900 102900]; also known as high red cell ATP syndrome. This autosomal dominant phenotype is characterized by increase of red blood cell ATP.<ref>PMID:9090535</ref>   Defects in PKLR are the cause of pyruvate kinase deficiency of red cells (PKRD) [MIM:[https://omim.org/entry/266200 266200]. A frequent cause of hereditary non-spherocytic hemolytic anemia. Clinically, pyruvate kinase-deficient patients suffer from a highly variable degree of chronic hemolysis, ranging from severe neonatal jaundice and fatal anemia at birth, severe transfusion-dependent chronic hemolysis, moderate hemolysis with exacerbation during infection, to a fully compensated hemolysis without apparent anemia.
== Function ==
[https://www.uniprot.org/uniprot/KPYR_HUMAN KPYR_HUMAN] Plays a key role in glycolysis (By similarity).
