What's a GeneRIF?

Exocyst structural changes associated with activation of tethering downstream of Rho/Cdc42 GTPases.
Title: Exocyst structural changes associated with activation of tethering downstream of Rho/Cdc42 GTPases.
Lipid-anchored Vti1 was fully active, and lipid-anchored Nyv1 permitted the reaction to proceed up to hemifusion, and lipid-anchored Vam3 interfered already before hemifusion.
Title: Vacuolar SNARE protein transmembrane domains serve as nonspecific membrane anchors with unequal roles in lipid mixing.
Data show that TVP23 interacts genetically with the yeast SNARE VTI1 and functions in retrograde transport from the early endosome to the late Golgi.
