Blue-light-activated phototropin2 trafficking from the cytoplasm to Golgi/post-Golgi vesicles
Phototropins are plasma membrane-localized UVA/blue light photoreceptors which mediate phototropism, inhibition of primary hypocotyl elongation, leaf positioning, chloroplast movements, and stomatal opening. Blue light irradiation activates the C-terminal serine/threonine kinase domain of phototropin which autophosphorylates the receptor. Arabidopsis thaliana encodes two phototropins, phot1 and...
متن کاملExclusion of Golgi Residents from Transport Vesicles Budding from Golgi Cisternae in Intact Cells
A central feature of cisternal progression/maturation models for anterograde transport across the Golgi stack is the requirement that the entire population of steady-state residents of this organelle be continuously transported backward to earlier cisternae to avoid loss of these residents as the membrane of the oldest (trans-most) cisterna departs the stack. For this to occur, resident protein...
متن کاملA resident Golgi protein is excluded from peri-Golgi vesicles in NRK cells.
To understand the structure and the function of the Golgi apparatus, it is essential to establish how resident Golgi enzymes are localized in only a few Golgi cisternae. In particular it is crucial to establish whether Golgi enzymes are retained specifically in cisternae, or if they are continuously transported from cisterna to cisterna. Here we report that a resident Golgi enzyme is largely ex...
متن کاملMicrotubule independent vesiculation of Golgi membranes and the reassembly of vesicles into Golgi stacks
We have recently shown that ilimaquinone (IQ) causes the breakdown of Golgi membranes into small vesicles (VGMs for vesiculated Golgi membranes) and inhibits vesicular protein transport between successive Golgi cisternae (Takizawa et al., 1993). While other intracellular organelles, intermediate filaments, and actin filaments are not affected, we have found that cytoplasmic microtubules are dep...
متن کاملVps10p transport from the trans-Golgi network to the endosome is mediated by clathrin-coated vesicles.
A native immunoisolation procedure has been used to investigate the role of clathrin-coated vesicles (CCVs) in the transport of vacuolar proteins between the trans-Golgi network (TGN) and the prevacuolar/endosome compartments in the yeast Saccharomyces cerevisiae. We find that Apl2p, one large subunit of the adaptor protein-1 complex, and Vps10p, the carboxypeptidase Y vacuolar protein receptor...
