Rab33B是一种膜运输调节剂,与Atg16L1(自噬的重要因子)直接相互作用,表明Rab33B参与了自噬的调节。在这里,我鉴定了一种未被鉴定的TBC蛋白OATL1作为Rab33B的失活因子,并解决了Rab33B在自噬过程中通过OATL1灭活Rab33B的功能。过表达OATL1会使内源性Rab33B失活,从而延迟MEF细胞的自噬体成熟。另一方面,Rab33B活性型突变体的过表达也延迟了自噬体的成熟。这些结果表明Rab33B参与了自噬体和溶酶体的融合,即自噬的后期过程。
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.
