CC   -!- FUNCTION: Component of the ERMES/MDM complex, which serves as a
CC       molecular tether to connect the endoplasmic reticulum (ER) and
CC       mitochondria. Components of this complex are involved in the control of
CC       mitochondrial shape and protein biogenesis, and function in
CC       nonvesicular lipid trafficking between the ER and mitochondria. MDM34
CC       is required for the interaction of the ER-resident membrane protein
CC       MMM1 and the outer mitochondrial membrane-resident beta-barrel protein
CC       MDM10. {ECO:0000255|HAMAP-Rule:MF_03105}.
CC   -!- SUBUNIT: Component of the ER-mitochondria encounter structure (ERMES)
CC       or MDM complex, composed of MMM1, MDM10, MDM12 and MDM34.
CC       {ECO:0000255|HAMAP-Rule:MF_03105}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion outer membrane {ECO:0000255|HAMAP-
CC       Rule:MF_03105}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_03105}. Note=The ERMES/MDM complex localizes to a few discrete
CC       foci (around 10 per single cell), that represent mitochondria-
CC       endoplasmic reticulum junctions. These foci are often found next to
CC       mtDNA nucleoids. {ECO:0000255|HAMAP-Rule:MF_03105}.
CC   -!- DOMAIN: Lacks alpha-helical transmembrane segments, suggesting that it
CC       resides in the membrane via beta-sheet conformations similar to those
CC       predicted for other outer membrane proteins and porin.
CC       {ECO:0000255|HAMAP-Rule:MF_03105}.
CC   -!- DOMAIN: The SMP-LTD domain is a barrel-like domain that can bind
CC       various types of glycerophospholipids in its interior and mediate their
CC       transfer between two adjacent bilayers. {ECO:0000255|HAMAP-
CC       Rule:MF_03105}.
CC   -!- PTM: Ubiquitinated by a SCF (SKP1-CUL1-F-box protein) E3 ubiquitin-
CC       protein ligase complex containing the F-box protein MDM30.
CC       Ubiquitination is important for mitochondrial integrity.
CC       {ECO:0000255|HAMAP-Rule:MF_03105}.
CC   -!- SIMILARITY: Belongs to the MDM34 family. {ECO:0000255|HAMAP-
CC       Rule:MF_03105}.
