"Homodimer. Component of the ER-mitochondria encounter structure (ERMES) or MDM complex, composed of @GENE_NAME@, MDM10, MDM12 and MDM34. A @GENE_NAME@ homodimer associates with one molecule of MDM12 on each side in a pairwise head-to-tail manner, and the SMP-LTD domains of @GENE_NAME@ and MDM12 generate a continuous hydrophobic tunnel for phospholipid trafficking."xsd:string
