STRINGSTRING
SRO77 protein (Saccharomyces cerevisiae) - STRING interaction network
"SRO77" - Protein with roles in exocytosis and cation homeostasis 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

SRO77Protein with roles in exocytosis and cation homeostasis; functions in docking and fusion of post-Golgi vesicles with plasma membrane; homolog of Sro7p and Drosophila lethal giant larvae tumor suppressor; interacts with SNARE protein Sec9p; Acts as an allosteric regulator of polarized exocytosis by promoting the targeted fusion of vesicles with the plasma membrane. Involved in maintenance of ion homeostasis in cells exposed to NaCl stress. May be involved in the targeting of the myosin proteins to their intrinsic pathways. Multicopy suppressor of RHO3. May also participate in the mainte [...] (1010 aa)    
Predicted Functional Partners:
MYO1
Type II myosin heavy chain, required for wild-type cytokinesis and cell separation; localizes to the actomyosin ring; binds to myosin light chains Mlc1p and Mlc2p through its IQ1 and IQ2 motifs respectively; Required for cell division (1928 aa)
       
 
  0.869
SEC9
t-SNARE protein important for fusion of secretory vesicles with the plasma membrane; similar to but not functionally redundant with Spo20p; SNAP-25 homolog; Component of a SNARE complex that may be the effector of SEC4 function in exocytosis (651 aa)
       
 
  0.722
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)
       
 
  0.722
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)
       
 
  0.702
DTR1
Putative dityrosine transporter, required for spore wall synthesis; expressed during sporulation; member of the major facilitator superfamily (DHA1 family) of multidrug resistance transporters; Prospore-specific dityrosine transporter responsible for translocation of dityrosine through the prospore membrane and required for the formation of the outermost layer of the spore (572 aa)
       
      0.682
SRO7
Effector of Rab GTPase Sec4p, forms a complex with Sec4p and t-SNARE Sec9p; involved in exocytosis and docking and fusion of post-Golgi vesicles with plasma membrane; homolog of Sro77p and Drosophila lgl tumor suppressor; Acts as an allosteric regulator of polarized exocytosis by promoting the targeted fusion of vesicles with the plasma membrane. Coordinates the spatial and temporal nature of both Rab- dependent tethering and SNARE-dependent membrane fusion of exocytic vesicles with the plasma membrane. Required for targeting of the sodium pumping ATPase ENA1 to the Cell Surface, thus [...] (1033 aa)
       
 
0.663
SPO20
Meiosis-specific subunit of the t-SNARE complex, required for prospore membrane formation during sporulation; similar to but not functionally redundant with Sec9p; SNAP-25 homolog; Required to maintain the prospore membrane to the nucleus during sporulation in order to capture the daughter nuclei and form the spores. Mediates the fusion of exocytic vesicles with the plasma membrane during sporulation through its interactions with the t-SNARE SSO1 and v-SNARE SNC2 (397 aa)
       
 
  0.610
SSO1
Plasma membrane t-SNARE involved in fusion of secretory vesicles at the plasma membrane and in vesicle fusion during sporulation; forms a complex with Sec9p that binds v-SNARE Snc2p; syntaxin homolog; functionally redundant with Sso2p; Required for vesicle fusion with the plasma membrane (290 aa)
       
 
  0.548
RPB4
RNA polymerase II subunit B32; forms two subunit dissociable complex with Rpb7p; involved in recruitment of 3’-end processing factors to transcribing RNA polymerase II complex and in export of mRNA to cytoplasm under stress conditions; also involved /.../anslation initiation; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Component of RNA polymerase II which synthesizes mRNA precursors and many functional non-coding RNAs. Pol II is the central component of the basal RNA polymerase II transcription mach [...] (221 aa)
