Summary: Enables GTPase activity and calcium ion binding activity. Involved in several processes, including mitochondrion inheritance; mitochondrion-endoplasmic reticulum membrane tethering; and phospholipid homeostasis. Located in mitochondrial outer membrane. Part of ERMES complex. Is active in mitochondria-associated endoplasmic reticulum membrane contact site. Used to study Parkinson's disease. Human ortholog(s) of this gene implicated in Parkinson's disease. Orthologous to human RHOT1 (ras homolog family member T1) and RHOT2 (ras homolog family member T2).

Preferred Names: ERMES complex Ca(2+)-binding regulatory GTPase GEM1

NP_009351.1

Outer mitochondrial membrane GTPase, subunit of the ERMES complex; potential regulatory subunit of the ERMES complex that links the ER to mitochondria and may promote inter-organellar calcium and phospholipid exchange as well as coordinating mitochondrial DNA replication and growth; cells lacking Gem1p contain collapsed, globular, or grape-like mitochondria; ortholog of metazoan Miro GTPases
