Comments [?]

case <OC:Saccharomyces>
Function Cooperates with the reticulon proteins RTN1 and RTN2 and the tubule-shaping DP1 family protein YOP1 to generate and maintain the structure of the tubular endoplasmic reticulum network. Has GTPase activity, which is required for its function in ER organization.
else case <OC:Fungi>
Function Cooperates with the reticulon proteins and tubule-shaping DP1 family proteins to generate and maintain the structure of the tubular endoplasmic reticulum network. Has GTPase activity, which is required for its function in ER organization.
else
Function Probable GTP-binding protein that may be involved in cell development.
end case
case <OC:Saccharomyces>
Subunit Interacts with RTN1 and YOP1; GTP binding is not required for these interactions.
end case
case <OC:Fungi>
Subcellular location Endoplasmic reticulum membrane; Multi-pass membrane protein. Note=Enriched in the cortical ER. Concentrated in punctae along the ER tubules.
else
Subcellular location Endoplasmic reticulum membrane; Multi-pass membrane protein.
end case
Similarity Belongs to the TRAFAC class dynamin-like GTPase superfamily. GB1/RHD3 GTPase family. RHD3 subfamily.
