Abstract
Piecemeal microautophagy of the nucleus (PMN) selectively removes and degrades small fragments of the Saccharomyces cerevisiae nucleus. Inter-organelle contact sites called nucleus-vacuole (NV) junctions determine the selectivity of PMN by establishing a platform for the biogenesis of PMN blebs and vesicles. PMN structures can be observed by fluorescence microscopy using GFP-tagged reporters; however, this approach is best supported with quantitative immunoblot assays of PMN-specific cargo degradation. Together, these assays should facilitate the further study of this fascinating but poorly understood autophagic process in different genetic backgrounds, physiological states, and environmental conditions.Entities:
