Summary: Enables pyruvate dehydrogenase (acetyl-transferring) kinase activity. Involved in several processes, including insulin receptor signaling pathway; regulation of acetyl-CoA biosynthetic process from pyruvate; and regulation of gluconeogenesis. Acts upstream of or within regulation of calcium-mediated signaling. Located in mitochondrion. Part of mitochondrial pyruvate dehydrogenase complex. Is expressed in heart. Orthologous to human PDK2 (pyruvate dehydrogenase kinase 2). [provided by Alliance of Genome Resources, Apr 2022]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
