CCZ1 protein (Saccharomyces cerevisiae) - STRING interaction network
"CCZ1" - Protein involved in vacuolar assembly, essential for autophagy and the cytoplasm-to-vacuole pathway in Saccharomyces cerevisiae
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
some 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

CCZ1Protein involved in vacuolar assembly, essential for autophagy and the cytoplasm-to-vacuole pathway; In complex with MON1, is required for multiple vacuole delivery pathways including the cytoplasm to vacuole transport (Cvt), autophagy, pexophagy and endocytosis. The CCZ1-MON1 complex acts at the fusion of vesicles with the vacuole, through its regulation of the SNARE complex during the coordinated priming and docking stages of fusion, and particularly at the stage of tethering/docking (704 aa)    
Predicted Functional Partners:
MON1
Protein required for fusion of cvt-vesicles and autophagosomes with the vacuole; associates, as a complex with Ccz1p, with a perivacuolar compartment; potential Cdc28p substrate; In complex with CCZ1, is required for multiple vacuole delivery pathways including the cytoplasm to vacuole transport (Cvt), autophagy, pexophagy and endocytosis. The CCZ1-MON1 complex acts at the fusion of vesicles with the vacuole, through its regulation of the SNARE complex during the coordinated priming and docking stages of fusion, and particularly at the stage of tethering/docking (644 aa)

YPT7
Rab family GTPase; GTP-binding protein of the rab family; required for homotypic fusion event in vacuole inheritance, for endosome-endosome fusion, similar to mammalian Rab7; Needed for homotypic vacuole fusion, the last step in the vacuole inheritance process (208 aa)

VAM7
Vacuolar SNARE protein that functions with Vam3p in vacuolar protein trafficking; has an N-terminal PX domain (phosphoinositide-binding module) that binds PtdIns-3-P and mediates membrane binding; SNAP-25 homolog; Essential for proper morphogenesis of the vacuole. May exist as structural reinforcement on the surface of the vacuolar membrane and be required for maintenance against rupture by osmotic pressure (316 aa)

VAM6
Vacuolar protein that plays a critical role in the tethering steps of vacuolar membrane fusion by facilitating guanine nucleotide exchange on small guanosine triphosphatase Ypt7p; Required for vacuolar assembly. Acts as component of the HOPS complex that acts during the docking stage of vacuole fusion. HOPS is an effector for the vacuolar Rab GTPase YPT7 and is required for vacuolar SNARE complex assembly. It remains bound to SNARE complexes after vacuole fusion (1049 aa)

ATG15
Lipase required for intravacuolar lysis of autophagic bodies and Cvt bodies; targeted to intravacuolar vesicles during autophagy via the multivesicular body (MVB) pathway; Lipase which is essential for lysis of subvacuolar cytoplasm to vacuole targeted bodies and intravacuolar autophagic bodies. Involved in the lysis of intravacuolar multivesicular body (MVB) vesicles. The intravacuolar membrane disintegration by ATG15 is critical to life span extension (520 aa)

ATG19
Receptor protein specific for the cytoplasm-to-vacuole targeting (Cvt) pathway; delivers cargo proteins aminopeptidase I (Lap4p) and alpha-mannosidase (Ams1p) to the phagophore assembly site for packaging into Cvt vesicles; Cargo-receptor protein involved in the cytoplasm to vacuole transport (Cvt) and in autophagy. Recognizes cargo proteins, such as APE4, LAP3, LAP4 and AMS1 and delivers them to the pre-autophagosomal structure for eventual engulfment by the autophagosome and targeting to the vacuole.
