Organelle zones for the Golgi stress response
Research abstract
When the capacity of the Golgi function becomes insufficient (Golgi stress), eukaryotic cells increase Golgi capacity by activating the homeostatic mechanism called the Golgi stress response. We are studying organelle zones in the Golgi apparatus, which transmit stress signals to the nucleus upon detection of Golgi stress. Since the function of the Golgi is quite diverse, several organelle zones for the Golgi stress response may exist, corresponding to each Golgi function. In detail, we are analyzing (1) the TFE3 zone for N-glycosylation, Golgi structure and vesicular transport, (2) the proteoglycan zone for proteoglycan-type glycosylation, (3) the mucin zone for mucin-type glycosylation and (4) the lipid pathway for lipid transport and glycosylation.
