CC   -!- FUNCTION: Cooperates with the reticulon proteins RTN1 and RTN2 and the
CC       tubule-shaping DP1 family protein YOP1 to generate and maintain the
CC       structure of the tubular endoplasmic reticulum network. Has GTPase
CC       activity, which is required for its function in ER organization.
CC       {ECO:0000255|HAMAP-Rule:MF_03109}.
CC   -!- SUBUNIT: Interacts with RTN1 and YOP1; GTP binding is not required for
CC       these interactions.
CC   -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC       {ECO:0000255|HAMAP-Rule:MF_03109}; Multi-pass membrane protein
CC       {ECO:0000255|HAMAP-Rule:MF_03109}. Note=Enriched in the cortical ER.
CC       Concentrated in punctae along the ER tubules. {ECO:0000255|HAMAP-
CC       Rule:MF_03109}.
CC   -!- SIMILARITY: Belongs to the TRAFAC class dynamin-like GTPase
CC       superfamily. GB1/RHD3 GTPase family. RHD3 subfamily.
CC       {ECO:0000255|PROSITE-ProRule:PRU01052}.
