RGA1 protein (Saccharomyces cerevisiae) - STRING interaction network
"RGA1" - GTPase-activating protein for the polarity-establishment protein Cdc42p 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

RGA1GTPase-activating protein for the polarity-establishment protein Cdc42p; implicated in control of septin organization, pheromone response, and haploid invasive growth; GTPase-activating protein (GAP) for CDC42 and/or RHO1. Negative regulator of the pheromone-response pathway through the STE20 protein kinase; acts at a step between the G-protein and the MAP kinase module. Dominant suppressor of bud emergence defect caused by deletion of IPL2/BEM2. Involved in the control of polarized cell growth and proper bud site selection (1007 aa)    
Predicted Functional Partners:
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
BEM1
Protein containing SH3-domains, involved in establishing cell polarity and morphogenesis; functions as a scaffold protein for complexes that include Cdc24p, Ste5p, Ste20p, and Rsr1p; Necessary for cell polarization during vegetative growth. May link the cytoskeleton to morphogenic determinants on the cell surface (551 aa)
       
 
  0.922
CLN2
G1 cyclin involved in regulation of the cell cycle; activates Cdc28p kinase to promote the G1 to S phase transition; late G1 specific expression depends on transcription factor complexes, MBF (Swi6p-Mbp1p) and SBF (Swi6p-Swi4p); Essential for the control of the cell cycle at the G1/S (start) transition. Interacts with the CDC28 protein kinase to form MPF (545 aa)
     
 
  0.921
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)
       
  0.910
RSR1
GTP-binding protein of the ras superfamily required for bud site selection, morphological changes in response to mating pheromone, and efficient cell fusion; localized to the plasma membrane; significantly similar to mammalian Rap GTPases; Involved in development of cell polarity during the cell division cycle, and essential for bud emergence. RSR1 and CDC24 interact functionally and perhaps physically (272 aa)
       
  0.902
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)
     
 
  0.890
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)

RGA2
GTPase-activating protein for the polarity-establishment protein Cdc42p; implicated in control of septin organization, pheromone response, and haploid invasive growth; regulated by Pho85p and Cdc28p; GTPase-activating protein (GAP) for CDC42 and/or RHO1 (1009 aa)
       
0.880
BUD14
Protein involved in bud-site selection, Bud14p-Glc7p complex is a cortical regulator of dynein; inhibitor of the actin assembly factor Bnr1p (formin); diploid mutants display a random budding pattern instead of the wild-type bipolar pattern; Important for bud site selection. Seems to be a regulatory subunit of the BUD14-GLC7 type-I phosphatase complex. The BUD14-GLC7 complex is necessary to regulate microtubule dynamics at the cortex and may function as a specific activator of the dynein complex (709 aa)
       
 
  0.874
YAK1
Serine-threonine protein kinase; component of a glucose-sensing system that inhibits growth in response to glucose availability; upon nutrient deprivation Yak1p phosphorylates Pop2p to regulate mRNA deadenylation, the co-repressor Crf1p to inhibit t /.../iption of ribosomal genes, and the stress-responsive transcription factors Hsf1p and Msn2p; nuclear localization negatively regulated by the Ras/PKA signaling pathway in the presence of glucose; Negative regulator of the cell cycle acting downstream of the cAMP-dependent protein kinase. Part of a glucose-sensing system involved in grow [...] (807 aa)
