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).
