SUMMARY PARAGRAPH for YPT10

Rab proteins are small Ras-related GTPases that function in multiple stages in membrane traffic. Rabs continuously cycle between the cytosol and membranes. The GDP-bound form of the Rab is complexed with guanine nucleotide dissociation inhibitor(GDI) in the cytosol and are recruited to the membranes with the help of GDF (GDI Displacement Factor) and by their prenylation by geranylgeranyl transferase II (GGTase II). The membrane-bound Rab is activated to the GTP-bound form by the guanine nucleotide exchange factors (GEFs) which then goes on to interact with downstream effectors. The GTPase-activating protein (GAP) stimulates the hydrolysis of GTP to GDP to inactivate the Rab. Eleven Rabs have been identified in yeast and more than 60 in mammalian cells (reviewed in 3, 4, 5).
