STRINGSTRING
YPT7 protein (Saccharomyces cerevisiae) - STRING interaction network
"YPT7" - Rab family GTPase 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

YPT7Rab 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)    
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)

GDI1
GDP dissociation inhibitor, regulates vesicle traffic in secretory pathways by regulating the dissociation of GDP from the Sec4/Ypt/rab family of GTP binding proteins; Regulates the GDP/GTP exchange reaction of SEC4 by inhibiting the dissociation of GDP from it, and the subsequent binding of GTP to SEC4. Plays an essential role in the yeast secretory pathway (451 aa)
     
 
  0.990
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)
       
 
  0.986
VPS41
Vacuolar membrane protein that is a subunit of the homotypic vacuole fusion and vacuole protein sorting (HOPS) complex; essential for membrane docking and fusion at the Golgi-to-endosome and endosome-to-vacuole stages of protein transport; Required for vacuolar assembly and vacuolar traffic. 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 (992 aa)
     
 
  0.986
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)
       
 
  0.979
VPS33
ATP-binding protein that is a subunit of the HOPS complex and of the CORVET tethering complex; essential for protein sorting, vesicle docking and fusion at the vacuole; Essential for vacuolar biogenesis, maturation and function. Involved in the sorting of vacuolar proteins from the Golgi apparatus and their targeting to the vacuole. 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 (691 aa)

MRS6
Rab escort protein, forms a complex with the Ras-like small GTPase Ypt1p that is required for the prenylation of Ypt1p by protein geranylgeranyltransferase type II (Bet2p-Bet4p); sequence similarity to mammalian choroideraemia gene; Substrate-binding subunit (component A) of the Rab geranylgeranyltransferase (GGTase) complex. Binds unprenylated Rab proteins and presents the substrate peptide to the catalytic component B. The component A is thought to be regenerated by transferring its prenylated Rab back to the donor membrane (603 aa)
     
 
  0.975
SEC17
Peripheral membrane protein required for vesicular transport between ER and Golgi, the ’priming’ step in homotypic vacuole fusion, and autophagy; stimulates the ATPase activity of Sec18p; has similarity to mammalian alpha-SNAP; SNARE complex protein that binds to cis-SNARE complexes on membranes and is required for vesicular transport between the endoplasmic reticulum and the Golgi apparatus and for homotypic vacuole fusion. During the priming step of membrane fusion, is released from cis-SNARE complexes by SEC18 to establish a pool of unpaired SNAREs, which are required for interactio [...] (292 aa)

CCZ1
Protein 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)
