STRINGSTRING
RPI1 protein (Saccharomyces cerevisiae) - STRING interaction network
"RPI1" - Putative transcriptional regulator 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

RPI1Putative transcriptional regulator; overexpression suppresses the heat shock sensitivity of wild-type RAS2 overexpression and also suppresses the cell lysis defect of an mpk1 mutation; Negative regulator of the Ras-cyclic AMP pathway. Negatively regulate the activity of normal but not mutationally activated Ras proteins. The down-regulatory effect of RPI1 requires the presence of one of the two Ras GTPase activators, IRA1 and IRA2 (407 aa)    
Predicted Functional Partners:
YAF9
Subunit of NuA4 histone H4 acetyltransferase and SWR1 complexes; may function to antagonize silencing near telomeres; interacts directly with Swc4p; has homology to human leukemogenic protein AF9; contains a YEATS domain; Component of the SWR1 complex which mediates the ATP- dependent exchange of histone H2A for the H2A variant HZT1 leading to transcriptional regulation of selected genes by chromatin remodeling. Component of the NuA4 histone acetyltransferase complex which is involved in transcriptional activation of selected genes principally by acetylation of nucleosomal histones H4 [...] (226 aa)
       
      0.727
MAK31
Non-catalytic subunit of N-terminal acetyltransferase of the NatC type; required for replication of dsRNA virus; member of the Sm protein family; Component of the NatC N-terminal acetyltransferase, which catalyzes acetylation of the N-terminus Met of L-A virus Gag protein. MAK31 is necessary for the structural stability of L-A double-stranded RNA-containing particles. Necessary for growth at 37 degrees Celsius as well as for maintenance of the killer plasmid (88 aa)
       
      0.727
WSC4
ER membrane protein involved in the translocation of soluble secretory proteins and insertion of membrane proteins into the ER membrane; may also have a role in the stress response but has only partial functional overlap with WSC1-3 (605 aa)
     
        0.700
PDE2
High-affinity cyclic AMP phosphodiesterase, component of the cAMP-dependent protein kinase signaling system, protects the cell from extracellular cAMP, contains readthrough motif surrounding termination codon; Controls the level of cAMP in yeast cells, together with the low-affinity cAMP phosphodiesterase (PDE1) (526 aa)
       
 
  0.686
RAS2
GTP-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)
       
 
  0.674
SLT2
Serine/threonine MAP kinase; involved in regulating maintenance of cell wall integrity, progression through the cell cycle, and nuclear mRNA retention in heat shock; required for mitophagy and pexophagy; affects recruitment of mitochondria to the ph /.../re assembly site (PAS); regulated by the PKC1-mediated signaling pathway; Serine/threonine protein kinase involved in a signal transduction pathway that plays a role in yeast cell morphogenesis and cell growth. This pathway seems to start by SMP3; then involve the kinase PKC1 that may act the BCK1 kinase that then phosphorylates MKK1 a [...] (484 aa)
       
 
  0.654
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)
       
 
  0.654
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)
       
 
  0.640
FLO11
GPI-anchored cell surface glycoprotein (flocculin); required for pseudohyphal formation, invasive growth, flocculation, and biofilms; transcriptionally regulated by the MAPK pathway (via Ste12p and Tec1p) and the cAMP pathway (via Flo8p); required f /.../ formation of fibrous interconnections between cells in a colony of a wild S. cerevisiae strain; Cell wall protein that participates in adhesive cell- cell interactions during yeast flocculation, a reversible, asexual and Ca(2+)-dependent process in which cells adhere to form aggregates (flocs) consisting of thousands of cells. Also in [...] (1367 aa)
