Methods to Monitor Nucleophagy in Yeast.

The selective degradation of nuclear components via autophagy, termed nucleophagy, is an essential process observed from yeasts to mammals and crucial for maintaining nucleus homeostasis and regulating nucleus functions. In the budding yeast Saccharomyces cerevisiae, nucleophagy occurs in two different manners: one involves autophagosome formation for the sequestration and vacuolar transport of nucleus-derived vesicles (NDVs), and the other proceeds with the invagination of the vacuolar membrane for the uptake of NDVs into the vacuole, termed macronucleophagy and micronucleophagy, respectively. This chapter describes methods to analyze and quantify activities of these nucleophagy pathways in yeast.
