CC -!- FUNCTION: Interferon-induced dynamin-like GTPase with antiviral
CC activity. {ECO:0000250}.
CC -!- SUBUNIT: Homooligomer. Oligomerizes into multimeric filamentous or
CC ring-like structures by virtue of its stalk domain. Oligomerization is
CC critical for GTPase activity, protein stability, and recognition of
CC viral target structures (By similarity). Interacts with TRPC1, TRPC3,
CC TRPC4, TRPC5, TRPC6 and TRPC7 (By similarity). Interacts with HSPA5 (By
CC similarity). Interacts with TUBB/TUBB5 (By similarity). Interacts with
CC DDX39A and DDX39B (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Endoplasmic reticulum
CC membrane {ECO:0000250}; Peripheral membrane protein {ECO:0000250};
CC Cytoplasmic side {ECO:0000250}. Cytoplasm, perinuclear region
CC {ECO:0000250}. Note=Binds preferentially to negatively charged
CC phospholipids. {ECO:0000250}.
CC -!- INDUCTION: By type I and type III interferons.
CC {ECO:0000269|PubMed:18062906}.
CC -!- DOMAIN: The C-terminal GTPase effector domain (GED) is involved in
CC oligomerization and viral target recognition. {ECO:0000250}.
CC -!- DOMAIN: The middle domain mediates self-assembly and oligomerization.
CC {ECO:0000250}.
CC -!- PTM: ISGylated. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the TRAFAC class dynamin-like GTPase
CC superfamily. Dynamin/Fzo/YdjA family. {ECO:0000255|PROSITE-
CC ProRule:PRU01055}.
