Analysis of tubular elongation in the network of endoplasmic reticulum

在拟南芥MM2d培养细胞中，研究表明，与酵母和动物细胞一样，网状蛋白(AtRTN)和atlastin GTP酶的同源物RHD3参与了内质网(ER)的管状形成。在内质网小管形成的条件下，RHD3能够与GTP结合并形成寡聚体。此外，内质网小管的形成可能受磷酸化的调节。

In the cultured cell of Arabidopsis, MM2d, it was shown that reticulon-like proteins(AtRTN) and RHD3, a homologue of atlastin GTPase, are involved in the tubular formation of endoplasmic reticulum(ER), as is case of yeast and animal cells. The RHD3 was able to bind to GTP, and form the oligomer under the conditions in which ER tubules were organized. Furthermore, ER tubule formation was suggested to be regulated by the phosphorylation.
