InnateDB Gene

IDBG-27748 (BCKDK)

Protein Structure

UniProt Annotation

Function

Catalyzes the phosphorylation and inactivation of the branched-chain alpha-ketoacid dehydrogenase complex, the key regulatory enzyme of the valine, leucine and isoleucine catabolic pathways. Key enzyme that regulate the activity state of the BCKD complex (By similarity). {ECO:0000250}.

Subcellular Localization

Mitochondrion matrix.

Disease Associations

Branched-chain ketoacid dehydrogenase kinase deficiency (BCKDKD) [MIM:614923]: A metabolic disorder characterized by autism, epilepsy, intellectual disability, and reduced branched- chain amino acids. {ECO:0000269PubMed:22956686}. Note=The disease is caused by mutations affecting the gene represented in this entry. A diet enriched in branched amino acids (BCAAs) allows to normalize plasma BCAA levels. This suggests that it may be possible to treat patients with mutations in BCKDK with BCAA supplementation.

Tissue Specificity

Ubiquitous.
