Structural highlights
Function
[RAC6_ARATH] May be involved in cell polarity control during the actin-dependent tip growth of pollen tubes.[1] [2] Inactive GDP-bound Rho GTPases reside in the cytosol, are found in a complex with Rho GDP-dissociation inhibitors (Rho GDIs), and are released from the GDI protein in order to translocate to membranes upon activation (By similarity).[3] [4]

Publication Abstract from PubMed
The small G protein ROP5 from the model plant Arabidopsis thaliana was purified and crystallized using the hanging-drop vapour-diffusion method. ROP5 crystals were obtained using PEG 3000 as precipitant and belong to space group P2(1). A data set was collected to 1.53 A resolution using synchrotron radiation at 100 K. A clear molecular-replacement solution was found using ROP4-GDP of the ROP4-GDP-PRONE8 complex as the search model.
