MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a member of the pyruvate dehydrogenase kinase family. The encoded protein phosphorylates pyruvate dehydrogenase, down-regulating the activity of the mitochondrial pyruvate dehydrogenase complex. Overexpression of this gene may play a role in both cancer and diabetes. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

PHENOTYPE: Mice homozygous for a knock-out allele exhibit decreased muscle contractile force. [provided by MGI curators]

Nature of Mutation

DNA sequencing using the SOLiD technique identified an A to G transition at position 414 of the Pdk2 transcript, in exon 3 of 11 total exons (NM_0133667).  Multiple transcripts are annotated in the Vega and Ensembl databases.  The mutation causes an aspartic acid to glycine change at amino acid 100 of the encoded protein.  The mutation has been confirmed by DNA sequencing using the Sanger method (see trace files for B5639).

Protein Function and Prediction

The 407 amino acid Pdk2 protein is one of four isozymes of pyruvate dehydrogenase kinase (PDK).  Pyruvate dehydrogenase functions in a mitochondrial multienzyme complex to catalyze the oxidative decarboxylation of pyruvate to acetyl-CoA, a reaction that links glycolysis and the Krebs cycle.  PDK inhibits the pyruvate dehydrogenase complex by phosphorylation of the E1 alpha subunit, thus contributing to the regulation of glucose metabolism (see Pdk1, Uniprot Q8BFP9).


The mutation is predicted to be benign by the PolyPhen-2 program.
