A fraction of this 2-oxoglutarate dehydrogenase complex also localizes in the nucleus and is required for lysine succinylation of histones: partners with KAT2A on chromatin and supplies succinyl-CoA to histone succinyltransferase KAT2A (PubMed:29211711). In monomeric form may have added moonlighting function as serine protease (PubMed:17404228).
