Summaries for TKTL1 Gene

Entrez Gene Summary for TKTL1 Gene

  • The protein encoded by this gene is a transketolase that acts as a homodimer and catalyzes the conversion of sedoheptulose 7-phosphate and D-glyceraldehyde 3-phosphate to D-ribose 5-phosphate and D-xylulose 5-phosphate. This reaction links the pentose phosphate pathway with the glycolytic pathway. Variations in this gene may be the cause of Wernicke-Korsakoff syndrome. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2011]

GeneCards Summary for TKTL1 Gene

TKTL1 (Transketolase-Like 1) is a Protein Coding gene. Diseases associated with TKTL1 include wernicke-korsakoff syndrome and nasopharyngitis. Among its related pathways are Carbon metabolism and Metabolism. GO annotations related to this gene include transketolase activity. An important paralog of this gene is TKT.
