CC -!- FUNCTION: Kinase that plays a key role in the regulation of glucose and
CC fatty acid metabolism and homeostasis via phosphorylation of the
CC pyruvate dehydrogenase subunits PDHA1 and PDHA2 (PubMed:22360721). This
CC inhibits pyruvate dehydrogenase activity, and thereby regulates
CC metabolite flux through the tricarboxylic acid cycle, down-regulates
CC aerobic respiration and inhibits the formation of acetyl-coenzyme A
CC from pyruvate. Inhibition of pyruvate dehydrogenase decreases glucose
CC utilization and increases fat metabolism. Mediates cellular responses
CC to insulin. Plays an important role in maintaining normal blood glucose
CC levels and in metabolic adaptation to nutrient availability. Via its
CC regulation of pyruvate dehydrogenase activity, plays an important role
CC in maintaining normal blood pH and in preventing the accumulation of
CC ketone bodies under starvation. Plays a role in the regulation of cell
CC proliferation and in resistance to apoptosis under oxidative stress.
CC Plays a role in p53/TP53-mediated apoptosis.
CC {ECO:0000269|PubMed:22360721}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-seryl-[pyruvate dehydrogenase E1 alpha subunit] = ADP
CC + H(+) + O-phospho-L-seryl-[pyruvate dehydrogenase E1 alpha subunit];

CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:23053;
CC Evidence={ECO:0000305|PubMed:22360721};
CC -!- SUBUNIT: Homodimer, and heterodimer with PDK1. Interacts with the
CC pyruvate dehydrogenase complex subunit DLAT, and is part of the
CC multimeric pyruvate dehydrogenase complex that contains multiple copies
CC of pyruvate dehydrogenase (E1), dihydrolipoamide acetyltransferase
CC (DLAT, E2) and lipoamide dehydrogenase (DLD, E3).
CC {ECO:0000269|PubMed:21190881}.
CC -!- INTERACTION:
CC Q9JK42; O08908: Pik3r2; NbExp=3; IntAct=EBI-643530, EBI-643570;
CC -!- SUBCELLULAR LOCATION: Mitochondrion matrix
CC {ECO:0000269|PubMed:21190881}.
CC -!- TISSUE SPECIFICITY: Detected in heart (at protein level).
CC {ECO:0000269|PubMed:21190881}.
CC -!- INDUCTION: Up-regulated by glucose and palmitic acid. Up-regulated by
CC PPARD. {ECO:0000269|PubMed:16631612, ECO:0000269|PubMed:17669420}.
CC -!- DISRUPTION PHENOTYPE: No visible phenotype, due to the fact that PDK2-
CC deficient mice have increased PDK1 levels (PubMed:21411764). Mice have
CC lower blood glucose levels in the fed state, but not after fasting.
CC Likewise, they display increased pyruvate dehydrogenase activity in
CC liver and skeletal muscle in the fed state, but not after fasting.
CC Fasting mice lacking both PDK2 and PDK4 show strongly decreased blood
CC glucose levels, increased circulating ketone body levels leading to
CC ketoacidosis with dangerously low blood pH levels, hypothermia, and
CC ultimately death (PubMed:22360721). {ECO:0000269|PubMed:21411764,
CC ECO:0000269|PubMed:22360721}.
CC -!- SIMILARITY: Belongs to the PDK/BCKDK protein kinase family.
CC {ECO:0000305}.
