TPK1 - thiamin pyrophosphokinase 1 Gene
Also Known as PP20; HTPK1; THMD5
Species: Homo sapiens
About TPK1
This gene has 13 transcripts (splice variants), 207 orthologues and is associated with 2 phenotypes. Ubiquitous expression in duodenum (RPKM 1.3), testis (RPKM 0.7) and 24 other tissues.
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 metabolism dysfunction syndrome-5. [provided by RefSeq, Apr 2017]
