Thiamine pyrophosphokinase 1 (TPK1)

Target
TPK1
Molecular classification
Enzyme, Kinase
01

Overview

Thiamine pyrophosphokinase 1 (TPK1) is an enzyme that catalyzes the phosphorylation of thiamine (vitamin B1) to thiamine pyrophosphate (TPP), a crucial coenzyme involved in central metabolic pathways. TPK1 plays an essential role in cellular energy metabolism. Deficiency or dysfunction can lead to impaired cerebral thiamine metabolism, resulting in neurodegeneration and neurological disorders. Its regulation has implications for nutritional deficiencies and cancer biology due to its impact on redox homeostasis under metabolic stress conditions.
