Gene Gene information from NCBI Gene database.
Entrez ID 27010
Gene name Thiamin pyrophosphokinase 1
Gene symbol TPK1
Synonyms (NCBI Gene)
HTPK1PP20THMD5
Chromosome 7
Chromosome location 7q35
Summary The protein encoded by this gene functions as a homodimer and catalyzes the conversion of thiamine to thiamine pyrophosphate, a cofactor for some enzymes of the glycolytic and energy production pathways. Defects in this gene are a cause of thiamine metabo
