LRG1 protein (Saccharomyces cerevisiae) - STRING interaction network
"LRG1" - Putative GTPase-activating protein 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

LRG1Putative GTPase-activating protein (GAP) involved in the Pkc1p-mediated signaling pathway that controls cell wall integrity; appears to specifically regulate 1,3-beta-glucan synthesis; Acts in signal transduction. Activates CDC42, RHO1 and RHO2. Negatively regulates 1,3-beta-glucan synthesis. May be responsible for the down-regulation of CDC42 during mating (1017 aa)    
Predicted Functional Partners:
RHO1
GTP-binding protein of the rho subfamily of Ras-like proteins, involved in establishment of cell polarity; regulates protein kinase C (Pkc1p) and the cell wall synthesizing enzyme 1,3-beta-glucan synthase (Fks1p and Gsc2p); Acts as a central regulator in the cell wall integrity signaling pathway, which is regulated by the cell cycle and in response to various types of cell wall stress. Integrates signals from different cell surface sensors, and activates a set of effectors, regulating processes including beta-glucan synthesis at the site of wall remodeling, gene expression related to c [...] (209 aa)
       
  0.997
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)
       
  0.993
PKC1
Protein serine/threonine kinase essential for cell wall remodeling during growth; localized to sites of polarized growth and the mother-daughter bud neck; homolog of the alpha, beta, and gamma isoforms of mammalian protein kinase C (PKC); Required for cell growth and for the G2->M transition of the cell division cycle. Mediates a protein kinase cascade; it activates BCK1 which itself activates MKK1/MKK2 (1151 aa)
     
 
  0.953
RHO2
Non-essential small GTPase of the Rho/Rac family of Ras-like proteins; involved in the establishment of cell polarity and in microtubule assembly (192 aa)
       
  0.953
RHO5
Non-essential small GTPase of the Rho/Rac subfamily of Ras-like proteins, likely involved in protein kinase C (Pkc1p)-dependent signal transduction pathway that controls cell integrity; Negatively regulates a MAP kinase branch, downstream of SLT2, of the PKC1-mediated signal transduction pathway (331 aa)
       
  0.946
ROM2
GDP/GTP exchange factor (GEF) for Rho1p and Rho2p; mutations are synthetically lethal with mutations in rom1, which also encodes a GEF; Stimulates the exchange of RHO1 GDP-bound form into GTP- bound form (1356 aa)
     
 
  0.932
HSP82
Hsp90 chaperone required for pheromone signaling and negative regulation of Hsf1p; docks with Tom70p for mitochondrial preprotein delivery; promotes telomerase DNA binding and nucleotide addition; interacts with Cns1p, Cpr6p, Cpr7p, Sti1p; Molecular chaperone that promotes the maturation, structural maintenance and proper regulation of specific target proteins involved in cell cycle control and signal transduction. Undergoes a functional cycle that is linked to its ATPase activity. The nucleotide-free form of the dimer is found in an open conformation in which the N-termini are not dim [...] (709 aa)
       
 
  0.923
GEM1
Evolutionarily-conserved tail-anchored outer mitochondrial membrane GTPase which regulates mitochondrial morphology; cells lacking Gem1p contain collapsed, globular, or grape-like mitochondria; not required for pheromone-induced cell death; Mitochondrial GTPase involved in mitochondrial trafficking. Probably involved in control of anterograde transport of mitochondria and their subcellular distribution (Probable) (662 aa)
     
 
  0.908
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)
       
  0.874
RHO4
Non-essential small GTPase of the Rho/Rac subfamily of Ras-like proteins, likely to be involved in the establishment of cell polarity; 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 (291 aa)
