Enables pyruvate kinase activity. Acts upstream of or within response to other organism. Located in cytoplasm and plasma membrane. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; respiratory system; and sensory organ. Used to study malaria and pyruvate kinase deficiency of red cells. Human ortholog(s) of this gene implicated in Gaucher's disease; congenital nonspherocytic hemolytic anemia; malaria; pyruvate kinase deficiency of red cells; and type 2 diabetes mellitus. Orthologous to human PKLR (pyruvate kinase L/R). [provided by Alliance of Genome Resources, Apr 2022]
