Ribbon representation of Rab9-GDP structure. A rainbow ramp colour-coding of blue to red is used to mimic chain trace from the N-terminus to the C-terminus. Both termini and the secondary-structure elements are labelled. GDP in the active site is shown in ball-and-stick. C atoms are colored grey, N atoms blue, O atoms red and P purple.

Rab9 is a novel anti-viral drug target. Please see the publication: J. Biol. Chem. 279, 40204-40208 (2004).
