Summary: Predicted to enable acyltransferase activity. Predicted to contribute to pyruvate dehydrogenase (NAD+) activity. Predicted to act upstream of or within mitochondrial acetyl-CoA biosynthetic process from pyruvate. Located in mitochondrion. Is expressed in several structures, including alimentary system; musculature; nervous system; sensory organ; and urinary system. Human ortholog(s) of this gene implicated in pyruvate decarboxylase deficiency. Orthologous to human PDHX (pyruvate dehydrogenase complex component X).

What's a GeneRIF?

In islet cells both fat and glucose regulate PDK gene and protein expression and indicate that hyperglycemia and hyperlipidemia contribute to the decline in diabetic islet PDH activity by increasing mRNA and protein expression of PDK.

T1a/podoplanin is first expressed in prox 1-positive lymphatic progenitor cells, with predominant localization in the luminal plasma membrane of lymphatic endothelial cells during later development.
Title: T1alpha/podoplanin deficiency disrupts normal lymphatic vasculature formation and causes lymphedema.

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.
