STRINGSTRING
RAS2 protein (Saccharomyces cerevisiae) - STRING interaction network
"RAS2" - GTP-binding protein that regulates the nitrogen starvation response, sporulation, and filamentous growth 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

RAS2GTP-binding protein that regulates the nitrogen starvation response, sporulation, and filamentous growth; farnesylation and palmitoylation required for activity and localization to plasma membrane; homolog of mammalian Ras proto-oncogenes; The S.cerevisiae Ras proteins modulate the activity of the adenylate cyclase catalytic subunit and therefore affect the biosynthesis of cyclic-AMP (322 aa)    
Predicted Functional Partners:
CDC25
Membrane bound guanine nucleotide exchange factor (GEF or GDP-release factor); indirectly regulates adenylate cyclase through activation of Ras1p and Ras2p by stimulating the exchange of GDP for GTP; required for progression through G1; Promotes the exchange of Ras-bound GDP by GTP. This protein positively controls the level of cellular cAMP at start, the stage at which the yeast cell division cycle is triggered (1589 aa)
     
  0.999
CYR1
Adenylate cyclase, required for cAMP production and cAMP-dependent protein kinase signaling; the cAMP pathway controls a variety of cellular processes, including metabolism, cell cycle, stress response, stationary phase, and sporulation; Plays essential roles in regulation of cellular metabolism by catalyzing the synthesis of a second messenger, cAMP (2026 aa)
     
  0.999
IRA2
GTPase-activating protein that negatively regulates RAS by converting it from the GTP- to the GDP-bound inactive form, required for reducing cAMP levels under nutrient limiting conditions, has similarity to Ira1p and human neurofibromin; Inhibitory regulator of the Ras-cyclic AMP pathway. Stimulates the GTPase activity of Ras proteins (3079 aa)
       
  0.998
IRA1
GTPase-activating protein that negatively regulates RAS by converting it from the GTP- to the GDP-bound inactive form, required for reducing cAMP levels under nutrient limiting conditions, mediates membrane association of adenylate cyclase; Inhibitory regulator of the Ras-cyclic AMP pathway in Saccharomyces cerevisiae. Stimulates the GTPase activity of Ras proteins (3092 aa)

STE20
Cdc42p-activated signal transducing kinase of the PAK (p21-activated kinase) family; involved in pheromone response, pseudohyphal/invasive growth, vacuole inheritance, down-regulation of sterol uptake; GBB motif binds Ste4p; MAP4K component of the MAPK pathway required for the mating pheromone response, haploid invasive growth and diploid pseudohyphal development. Links the pheromone response G-protein beta gamma subunits to downstream signaling components. Needed for mating in haploid cells, induction of a mating-specific gene FUS1, induction of mating-specific morphologies, and phero [...] (939 aa)
       
  0.984
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)
     
  0.983
GPA2
Nucleotide binding alpha subunit of the heterotrimeric G protein; interacts with the receptor Gpr1p, has signaling role in response to nutrients; required for the recruitment of Ras-GTP at the plasma membrane and in the nucleus; Alpha subunit of the heterotrimeric guanine nucleotide- binding protein (G protein) involved in glucose-induced cAMP signaling. Binds to its cognate transmembrane receptor GPR1, which senses extracellular carbon sources, and activates cAMP-PKA signaling and governs diploid pseudohyphal differentiation and haploid invasive growth. The G protein beta-mimic protei [...] (449 aa)

GPR1
Plasma membrane G protein coupled receptor (GPCR); interacts with the heterotrimeric G protein alpha subunit, Gpa2p, and with Plc1p; sensor that integrates nutritional signals with the modulation of cell fate via PKA and cAMP synthesis; Seems to associate with GPA2 and act as G protein- coupled receptor that senses glucose and controls filamentous growth. It acts upstream of adenylate cyclase and is required for glucose activation of cAMP synthesis in concert with a glucose phosphorylation-dependent mechanism (961 aa)

UBI4
Ubiquitin, becomes conjugated to proteins, marking them for selective degradation via the ubiquitin-26S proteasome system; essential for the cellular stress response; encoded as a polyubiquitin precursor comprised of 5 head-to-tail repeats; Ubiquitin exists either covalently attached to another protein, or free (unanchored). When covalently bound, it is conjugated to target proteins via an isopeptide bond either as a monomer (monoubiquitin), a polymer linked via different Lys residues of the ubiquitin (polyubiquitin chains) or a linear polymer linked via the initiator Met of the ubiqui [...] (381 aa)

BCY1
Regulatory subunit of the cyclic AMP-dependent protein kinase (PKA), a component of a signaling pathway that controls a variety of cellular processes, including metabolism, cell cycle, stress response, stationary phase, and sporulation; Regulatory subunit of the cyclic AMP-dependent protein kinase (PKA), an effector of the Ras/cAMP pathway. Inhibits PKA activity in the absence of cAMP. cAMP activates PKA and promotes growth and proliferation in response to good nutrient conditions. Together with ZDS1, provides a negative feedback control on the cell wall integrity-signaling pathway by [...] (416 aa)
