Outline of Final Research Achievements

In this study, we analyzed some atypical small GTPases and found that 1) ARL8 is involved in phagosome-lysosome fusion and required for efficient removal of apoptotic cells; 2) both the N-terminal palmitoylation and the C-terminal RVxP motif of Arl13b are required for the ciliary localization of Arl13b; 3) Di-Ras2 activity may be regulated via interaction with SmgGDS; 4) C. elegans Di-Ras homolog functions as a positive regulator for acetylcholine release from neuronal cells.
