膜转运调节因子Rab33B与自噬必需因子Atg16L1的直接相互作用表明,Rab33B参与了自噬的调节。在这里,我确定了一个未知的TBC蛋白OATL1作为Rab33B的失活因子,并探讨了Rab33B在自噬中的作用。过表达OATL1会使内源性Rab33B失活,从而延迟MEF细胞的自噬成熟。另一方面,Rab33B活性突变体的过表达也延迟了自噬小体的成熟。这些结果表明,Rab33B在自噬和溶酶体之间的融合中发挥了作用,这是自噬的后续过程。
英文摘要
The direct interaction of Rab33B, a regulator of membrane trafficking, with Atg16L1, an essential factor for autophagy, suggests involvement of Rab33B in the regulation of autophagy. Here, I identified OATL1, an uncharacterized TBC protein, as an inactivation factor of Rab33B and addressed the function of Rab33B in autophagy to inactivate Rab33B by OATL1. Overexpression of OATL1, which would inactivate endogenous Rab33B, delayed autophagosomal maturation in MEF cells. On the other hand, overexpression of active-form mutant of Rab33B also delayed autophagosomal maturation. These results indicate that Rab33B plays a role in the fusion between autophagosomes and lysosomes, a later process of autophagy.
