'''GppNHp-Bound Rab33 GTPase'''<br />


==Overview==
==GppNHp-Bound Rab33 GTPase==
Rab GTPases regulate all stages of membrane trafficking, including vesicle, budding, cargo sorting, transport, tethering and fusion. In the inactive, (GDP-bound) conformation, accessory factors facilitate the targeting of, Rab GTPases to intracellular compartments. After nucleotide exchange to, the active (GTP-bound) conformation, Rab GTPases interact with, functionally diverse effectors including lipid kinases, motor proteins and, tethering complexes. How effectors distinguish between homologous Rab, GTPases represents an unresolved problem with respect to the specificity, of vesicular trafficking. Using a structural proteomic approach, we have, determined the specificity and structural basis underlying the interaction, of the multivalent effector rabenosyn-5 with the Rab family. The results, demonstrate that even the structurally similar effector domains in, rabenosyn-5 can achieve highly selective recognition of distinct subsets, of Rab GTPases exclusively through interactions with the switch and, interswitch regions. The observed specificity is determined at a, family-wide level by structural diversity in the active conformation, which governs the spatial disposition of critical conserved recognition, determinants, and by a small number of both positive and negative sequence, determinants that allow further discrimination between Rab GTPases with, similar switch conformations.
