Outline of Final Research Achievements |
GGAs (GGA1,2,3) and AP-1 are membrane trafficking associated molecules and they function as clathrin adaptors. Their functions have been investigated in terms of quality control of protein using cell lines. Depletion of GGA2 or AP-1 complex decreased EGFR expression at protein level, reflecting enhanced lysosomal degradation of EGFR. This result suggests that GGA2 and AP-1 complex are involved in protein transport of transmembrane protein at the post-Golgi compartments to regulate the turnover. Also, this raises a possibility that the malfunction of GGAs and AP-1 could influence pathologies such as neurodegenerative diseases or cancer.
