Summary: The pyruvate dehydrogenase (PDH) complex is a nuclear-encoded mitochondrial multienzyme complex that catalyzes the overall conversion of pyruvate to acetyl-CoA and carbon dioxide, and provides the primary link between glycolysis and the tricarboxylic acid (TCA) cycle. The PDH complex is composed of multiple copies of three enzymatic components: pyruvate dehydrogenase (E1), dihydrolipoamide acetyltransferase (E2) and lipoamide dehydrogenase (E3). The E1 enzyme is a heterotetramer of two alpha and two beta subunits. This gene encodes the E1 beta subunit. Mutations in this gene are associated with pyruvate dehydrogenase E1-beta deficiency. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Mar 2012]

Building on evidence that PDH activity depends on the stability of a multi-protein PDH complex, the authors found that the PDH-E1beta subunit of the PDH complex is downregulated to inhibit PDH activity under conditions of prolonged hypoxia which establishs the specific mechanism through which PDH acts as an oncogenic factor by tuning glycolytic metabolism in cancer cells.

PDHB was downregulated in nasopharyngeal carcinoma cells. Forced expression of PDHB in NPC cells inhibited cell growth and migration, while knocking down the expression of PDHB promoted the growth, migration, and tumorigenesis of NPC cells. PDHB inhibited ERK signaling and cell growth driven by RasV12.

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.

NR_033384.2 RNA Sequence

Status: REVIEWED

Description

Transcript Variant: This variant (3) is alternatively spliced at the 5' end compared to variant 1. It is represented as non-coding because the use of the 5'-most translational start codon, as used in variant 1, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
