| Post Translational Modifications | Prenylated.prenylation is required for RAB24 localization to autophagosomes. Isoprenylation is inefficient compared to other Rab family members. Phosphorylated at Tyr-17 and Tyr-172. Cytosolic pool of RAB24 is more phosphorylated than the membrane-associated pool. |
| Function | The small GTPases Rab are key regulators of intracellular membrane trafficking, from the formation of transport vesicles to their fusion with membranes. Rabs cycle between an inactive GDP-bound form and an active GTP-bound form that is able to recruit to membranes different sets of downstream effectors directly responsible for vesicle formation, movement, tethering and fusion. RAB24 is an atypical RAB protein that presents low GTPase activity and thereby exists predominantly in the GTP-bound active state. RAB24 is required for the clearance of late autophagic vacuoles under basal conditions. It is not needed for starvation-induced autophagy. Involved in the modulation of meiotic apparatus assembly and meiotic progression during oocyte maturation, possibly through regulation of kinetochore-microtubule interaction. |
