STRINGSTRING
SEC18 protein (Saccharomyces cerevisiae) - STRING interaction network
"SEC18" - ATPase required for vesicular transport between ER and Golgi, the 'priming' step in homotypic vacuole fusion, autophagy, and protein secretion 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

SEC18ATPase required for vesicular transport between ER and Golgi, the ’priming’ step in homotypic vacuole fusion, autophagy, and protein secretion; releases Sec17p from SNAP complexes; has similarity to mammalian NSF; Required for vesicle-mediated transport. Catalyzes the fusion of transport vesicles within the Golgi cisternae. Is also required for transport from the endoplasmic reticulum to the Golgi stack. Seems to function as a fusion protein required for the delivery of cargo proteins to all compartments of the Golgi stack independent of vesicle origin (758 aa)    
Predicted Functional Partners:
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)
     
  0.999
SED5
cis-Golgi t-SNARE syntaxin required for vesicular transport between the ER and the Golgi complex, binds at least 9 SNARE proteins; Required for vesicular transport between the endoplasmic reticulum and the Golgi complex. Acts as a target organelle soluble NSF attachment protein receptor (t-SNARE) (340 aa)
     
  0.997
YKT6
Vesicle membrane protein (v-SNARE) with acyltransferase activity; involved in trafficking to and within the Golgi, endocytic trafficking to the vacuole, and vacuolar fusion; membrane localization due to prenylation at the carboxy-terminus (200 aa)
     
  0.994
SLY1
Hydrophilic protein involved in ER/Golgi vesicle trafficking; SM (Sec1/Munc-18) family protein that binds the tSNARE Sed5p and stimulates its assembly into a trans-SNARE membrane-protein complex; Able to suppress the functional loss of YPT1. SLY1 is essential for cell viability. May interact indirectly, or directly with YPT1 (666 aa)
     
 
  0.993
NYV1
v-SNARE component of the vacuolar SNARE complex involved in vesicle fusion; inhibits ATP-dependent Ca(2+) transport activity of Pmc1p in the vacuolar membrane; Vacuolar v-SNARE required for docking. Only involved in homotypic vacuole fusion. Required for Ca(2+) efflux from the vacuolar lumen, a required signal for subsequent membrane fusion events, by inhibiting vacuolar Ca(2+)-ATPase PMC1 and promoting Ca(2+) release when forming trans-SNARE assemblies during the docking step (253 aa)
     
 
  0.990
SEC1
Sm-like protein involved in docking and fusion of exocytic vesicles; binds to assembled SNARE complexes at the membrane and stimulates membrane fusion; localization to sites of secretion (bud neck and bud tip) is dependent on SNARE function; Involved in the final stage of protein secretion (724 aa)
     
 
  0.989
SNC1
Vesicle membrane receptor protein (v-SNARE) involved in the fusion between Golgi-derived secretory vesicles with the plasma membrane; proposed to be involved in endocytosis; member of the synaptobrevin/VAMP family of R-type v-SNARE proteins; SNC1 and SNC2 are vesicle-targeting proteins essential for normal secretory traffic between the Golgi and the plasma membrane. They may also be involved in vesicle fusion (117 aa)
     
  0.986
VTI1
Protein involved in cis-Golgi membrane traffic; v-SNARE that interacts with two t-SNARES, Sed5p and Pep12p; required for multiple vacuolar sorting pathways; t-SNARE found in various SNARE complexes involved in multiple transport pathways. The composition of the t-SNARE complexes is specific for a limited number of v-SNAREs and therefore allows only the vesicles carrying the matching v-SNARE to fuse (217 aa)
       
  0.985
GOS1
v-SNARE protein involved in Golgi transport, homolog of the mammalian protein GOS-28/GS28; Involved in transport from the ER to the Golgi apparatus as well as in intra-Golgi transport. It belongs to a super-family of proteins called t-SNAREs or soluble NSF (N-ethylmaleimide- sensitive factor) attachment protein receptor. Rescues alpha- factor maturation defects (223 aa)
     
  0.982
SNC2
Vesicle membrane receptor protein (v-SNARE) involved in the fusion between Golgi-derived secretory vesicles with the plasma membrane; member of the synaptobrevin/VAMP family of R-type v-SNARE proteins; SNC1 and SNC2 are vesicle-targeting proteins essential for normal secretory traffic between the Golgi and the plasma membrane. They may also be involved in vesicle fusion (115 aa)
