Tpk1 Gene Summary [Rat]
Predicted to enable UTP thiamine diphosphokinase activity; identical protein binding activity; and thiamine diphosphokinase activity. Predicted to be involved in regulation of acetyl-CoA biosynthetic process from pyruvate and thiamine diphosphate biosynthetic process. Predicted to act upstream of or within thiamine metabolic process. Predicted to be active in cytosol. Human ortholog(s) of this gene implicated in inherited metabolic disorder. Orthologous to human TPK1 (thiamin pyrophosphokinase 1). [provided by Alliance of Genome Resources, Apr 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Tpk1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
