This is the three-helix bundle (3HB) domain found at the C-terminal of Sey1 from yeast and RHD3 from Arabidopsis, GTP-binding proteins involved in homotypic membrane fusion of the endoplasmic reticulum [1,2,3]. This is a stalk-like domain composed of four 3HBs that interacts with its own GTPase domain and that of a neighbouring molecule, to undergo major conformational changes during the GTP cycle to drive membrane fusion [3].
Root hair defective 3 GTP-binding protein (RHD3) GTPase domain
This is the GTPase domain of several eukaryotic root hair defective 3 (RHD3) like GTP-binding proteins, including RHD3 from Arabidopsis and Sey1 from yeast [1,2,3], which are involved in homotypic membrane fusion of the endoplasmic reticulum [3]. Thi ...
This is the GTPase domain of several eukaryotic root hair defective 3 (RHD3) like GTP-binding proteins, including RHD3 from Arabidopsis and Sey1 from yeast [1,2,3], which are involved in homotypic membrane fusion of the endoplasmic reticulum [3]. This domain binds GTP and forms dimers with other molecule for membrane tethering [3].
