A human thiamine pyrophosphokinase cDNA clone (hTPK1) was isolated and sequenced. When the intact hTPK1 open reading frame was expressed as a histidine-tag fusion protein in Escherichia coli, marked enzyme activity was detected in the bacterial cells. The hTPK1 mRNA was widely expressed in various human tissues at a very low level, and the mRNA content in cultured fibroblasts was unaffected by the thiamine concentration of the medium. The chromosome localization of the hTPK1 gene was assigned to 7q34.
