摘要

In Saccharomyces cerevisiae, and , two small GTP-binding proteins that regulate membrane traffic in the secretory and endocytic pathways, are also necessary for autophagy. To gain information about potential partners of and specifically in autophagy, we carried out a high copy number suppressor screen to identify genes that when overexpressed suppress the rapamycin sensitivity phenotype of Δ and Δ strains at 37°. From the screen results, we selected , , , , , , and , either membrane traffic or autophagy regulators, to further test whether they can suppress the specific autophagy defects of Δ and Δ strains. As a result, we identified , href="http://www.yeastgenome.org/locus/S000003573/overview" data-ga-action="click_feat_suppl" ref="reftype=extlink&article-id=5295583&issue-id=287092&journal-id=1684&FROM=Article%7CFront%20Matter&TO=External%7CLink%7CURI" target="_blank">SNX4, and href="http://www.yeastgenome.org/locus/S000003619/overview" data-ga-action="click_feat_suppl" ref="reftype=extlink&article-id=5295583&issue-id=287092&journal-id=1684&FROM=Article%7CFront%20Matter&TO=External%7CLink%7CURI" target="_blank">TAX4 to be specific suppressors for the href="http://www.yeastgenome.org/locus/S000000368/overview" data-ga-action="click_feat_suppl" ref="reftype=extlink&article-id=5295583&issue-id=287092&journal-id=1684&FROM=Article%7CFront%20Matter&TO=External%7CLink%7CURI" target="_blank">arl1Δ strain, and href="http://www.yeastgenome.org/locus/S000002637/overview" data-ga-action="click_feat_suppl" ref="reftype=extlink&article-id=5295583&issue-id=287092&journal-id=1684&FROM=Article%7CFront%20Matter&TO=External%7CLink%7CURI" target="_blank">IVY1 and href="http://www.yeastgenome.org/locus/S000006070/overview" data-ga-action="click_feat_suppl" ref="reftype=extlink&article-id=5295583&issue-id=287092&journal-id=1684&FROM=Article%7CFront%20Matter&TO=External%7CLink%7CURI" target="_blank">ATG5 for the href="http://www.yeastgenome.org/locus/S000004252/overview" data-ga-action="click_feat_suppl" ref="reftype=extlink&article-id=5295583&issue-id=287092&journal-id=1684&FROM=Article%7CFront%20Matter&TO=External%7CLink%7CURI" target="_blank">ypt6Δ strain.
