Outline of Final Research Achievements

A well-accepted role for tethering factors is the initial attachment of transport carriers to acceptor membranes prior to fusion. Golgins, long coiled-coil proteins that localize to particular Golgi subdomains, are candidate tethering factors. In this study, we report that two type of golgins, golgin-84 and p230, interact with microtubule related proteins. Protein interaction analyses have revealed that golgin-84 interact with kinesin2 subunit Kif3C, and plays a role for transport to lysozom from the Golgi. We investigated the role of p230 and microtubule actin crosslinking protein 1 (MACF1), in amino acid starvation-induced membrane transport. p230 or MACF1 knockdown (KD) cells failed to mAtg9 recruitment to phagophores from the TGN, The interaction between a tether and microtubule related protein brings the idea that tethers plays not only in the vesicle tethering process but also in the initial event to direct a vesicle to its correct intracellular destination.
