CCZ1

CVT16, L000004556, L000004776, S000029129, YBR131W
Subunit of a heterodimeric guanine nucleotide exchange factor (GEF); subunit of the Mon1-Ccz1 GEF complex, which stimulates nucleotide exchange and activation of Ypt7p, a Rab family GTPase involved in membrane tethering and fusion events at the late endosome and vacuole; GEF activity is stimulated by membrane association and anionic phospholipids; involved in localizing Ypt7p to the vacuolar membrane; required for macroautophagy, the CVT pathway and mitophagy
Saccharomyces cerevisiae (S288c)

ZRC1

OSR1, Zn(2+) transporter ZRC1, L000002570, YMR243C
Vacuolar membrane zinc transporter; transports zinc from cytosol to vacuole for storage; also has role in resistance to zinc shock resulting from sudden influx of zinc into cytoplasm; human ortholog SLC30A10 functions as a Mn transporter and mutations in SLC30A10 cause neurotoxic accumulation of Mn in liver and brain; ZRC1 has a paralog, COT1, that arose from the whole genome duplication

Dosage Rescue

A genetic interaction is inferred when over expression or increased dosage of one gene rescues the lethality or growth defect of a strain that is mutated or deleted for another gene.

Multiple functions of the vacuolar sorting protein Ccz1p in Saccharomyces cerevisiae.

Hoffman-Sommer M, Migdalski A, Rytka J, Kucharczyk R

The CCZ1 (YBR131w) gene encodes a protein required for fusion of various transport intermediates with the vacuole. Ccz1p, in a complex with Mon1p, is a close partner of Ypt7p in the processes of fusion of endosomes to vacuoles and homotypic vacuole fusion. In this work, we exploited the Ca(2+)-sensitivity of the ccz1Delta mutant to identify genes specifically interacting with CCZ1, ... [more]
