Protein attributes

Sequence length	327 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Component of the mitochondrial outer membrane sorting assembly machinery (SAM or TOB) complex, which is required for the sorting of proteins with complicated topology, such as beta-barrel proteins, to the mitochondrial outer membrane after import by the TOM complex. Ref.6
Subunit structure	Component of the mitochondrial outer membrane sorting assembly machinery (SAM or TOB) complex, which at least consists of SAM35, SAM37 and SAM50. SAM37 interacts with TOM70.
Subcellular location	Mitochondrion outer membrane; Multi-pass membrane protein.
Miscellaneous	Present with 1580 molecules/cell in log phase SD medium. Ref.7
