Human PCK1 encoding phosphoenolpyruvate carboxykinase is located on chromosome 20q13.2.
Cytoplasmic liver phosphoenolpyruvate carboxykinase (GTP) (PEPCK) catalyzes a rate-limiting step in gluconeogenesis. Primers derived from the rat liver PEPCK sequence were used to amplify a portion of the human liver cDNA and to screen a YAC library of human genomic DNA. The sequences of human and rat PEPCK cDNA differed at 16% of the nucleotides compared (45/291). Analysis of a human/rodent hybrid mapping panel demonstrated concordant segregation of PCK1 with chromosome 20. Fluorescence in situ hybridization with YAC DNA further localized PCK1 to subband 20q13.2.
