STRINGSTRING
SEC5 protein (Saccharomyces cerevisiae) - STRING interaction network
"SEC5" - Essential 107kDa subunit of the exocyst complex (Sec3p, Sec5p, Sec6p, Sec8p, Sec10p, Sec15p, Exo70p, and Exo84p), which has the essential function of mediating polarized targeting of secretory vesicles to active sites of exocytosis 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

SEC5Essential 107kDa subunit of the exocyst complex (Sec3p, Sec5p, Sec6p, Sec8p, Sec10p, Sec15p, Exo70p, and Exo84p), which has the essential function of mediating polarized targeting of secretory vesicles to active sites of exocytosis; Component of the exocyst complex involved in the docking of exocytic vesicles with fusion sites on the plasma membrane (971 aa)    
Predicted Functional Partners:
EXO70
Subunit of the exocyst complex (Sec3p, Sec5p, Sec6p, Sec8p, Sec10p, Sec15p, Exo70p, and Exo84p), which directs secretory vesicles to active sites of exocytosis; acts with Sec3p in membrane targeting of the exocyst via PI(4,5)P2 binding; Involved in the secretory pathway as part of the exocyst complex which tethers secretory vesicles to the sites of exocytosis. Plays a role in the assembly of the exocyst (623 aa)
     
  0.999
SEC10
Essential 100kDa subunit of the exocyst complex; the exocyst mediates polarized targeting and tethering of post-Golgi secretory vesicles to active sites of exocytosis at the plasma membrane prior to SNARE-mediated fusion; Component of the exocyst complex involved in the docking of exocytic vesicles with fusion sites on the plasma membrane (871 aa)
     
  0.999
SEC8
Essential 121kDa subunit of the exocyst complex (Sec3p, Sec5p, Sec6p, Sec8p, Sec10p, Sec15p, Exo70p, and Exo84p), which has the essential function of mediating polarized targeting of secretory vesicles to active sites of exocytosis; Component of the exocyst complex involved in the docking of exocytic vesicles with fusion sites on the plasma membrane (1065 aa)
     
  0.999
SEC3
Subunit of the exocyst complex (Sec3p, Sec5p, Sec6p, Sec8p, Sec10p, Sec15p, Exo70p, Exo84p) which mediates targeting of post-Golgi vesicles to sites of active exocytosis; Sec3p specifically is a spatial landmark for secretion; Component of the exocyst complex involved in the docking of exocytic vesicles with fusion sites on the plasma membrane (1336 aa)
     
  0.999
EXO84
Essential protein with dual roles in spliceosome assembly and exocytosis; the exocyst complex (Sec3p, Sec5p, Sec6p, Sec8p, Sec10p, Sec15p, Exo70p, and Exo84p) mediates polarized targeting of secretory vesicles to active sites of exocytosis; Involved in the secretory pathway as part of the exocyst complex which tethers secretory vesicles to the sites of exocytosis. Plays a role in both the assembly of the exocyst and the polarization of this complex to specific sites of the plasma membrane for exocytosis and to the budding site. Also involved in assembly of the spliceosome (753 aa)
     
  0.999
SEC15
Essential 113kDa subunit of the exocyst complex (Sec3p, Sec5p, Sec6p, Sec8p, Sec10p, Sec15p, Exo70p, and Exo84p), which mediates polarized targeting of vesicles to active sites of exocytosis; Sec15p associates with Sec4p and vesicles; Component of the exocyst complex involved in the docking of exocytic vesicles with fusion sites on the plasma membrane (910 aa)
     
  0.999
SEC6
Essential 88kDa subunit of the exocyst complex, which mediates polarized targeting of secretory vesicles to active sites of exocytosis; dimeric form of Sec6p interacts with Sec9p in vitro and inhibits t-SNARE assembly; Component of the exocyst complex involved in the docking of exocytic vesicles with fusion sites on the plasma membrane (805 aa)
     
  0.999
CDC42
Small rho-like GTPase, essential for establishment and maintenance of cell polarity; mutants have defects in the organization of actin and septins; Involved in development of cell polarity during the cell division cycle, and essential for bud emergence. Affects signaling in the pheromone-response pathway through the STE20 protein kinase. Negatively regulated by the GTPase-activating proteins RGA1, BEM3, and BEM4 (191 aa)
       
  0.938
SEC4
Rab family GTPase essential for vesicle-mediated exocytic secretion and autophagy; associates with the exocyst component Sec15p and may regulate polarized delivery of transport vesicles to the exocyst at the plasma membrane; Involved in exocytosis. Maybe by regulating the binding and fusion of secretory vesicles with the cell surface. The GTP- bound form of SEC4 may interact with an effector, thereby stimulating its activity and leading to exocytotic fusion. SEC4 may be an upstream activator of the 19.5S SEC8/SEC15 particle. SEC4 probably interacts directly with SEC8; it could serve as [...] (215 aa)

RHO3
Non-essential small GTPase of the Rho/Rac family of Ras-like proteins; involved in the establishment of cell polarity; GTPase activity positively regulated by the GTPase activating protein (GAP) Rgd1p; Plays an important role in cell growth. Required to keep the uninucleated state. May be involved in the organization of the cytoskeleton which affects microtubule functions. Most likely RHO3 and RHO4 of S.cerevisiae regulate partially overlapping but different pathways (231 aa)
