Mouse Pyruvate Dehydrogenase Protein X Component, Mitochondrial, PDHX ELI

Required for anchoring dihydrolipoamide dehydrogenase (E3) to the dihydrolipoamide transacetylase (E2) core of the pyruvate dehydrogenase complexes of eukaryotes.

This specific binding is essential for a functional PDH complex (By similarity).
