STRINGSTRING
PGU1 protein (Saccharomyces cerevisiae) - STRING interaction network
"PGU1" - Endo-polygalacturonase, pectolytic enzyme that hydrolyzes the alpha-1,4-glycosidic bonds in the rhamnogalacturonan chains in pectins 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

PGU1Endo-polygalacturonase, pectolytic enzyme that hydrolyzes the alpha-1,4-glycosidic bonds in the rhamnogalacturonan chains in pectins (361 aa)    
Predicted Functional Partners:
KSS1
Mitogen-activated protein kinase (MAPK) involved in signal transduction pathways that control filamentous growth and pheromone response; the KSS1 gene is nonfunctional in S288C strains and functional in W303 strains; Together with closely related FUS3, KSS1 is the final kinase in the signal transduction cascade regulating activation/repression of the mating and filamentation pathways, induced by pheromone and nitrogen/carbon limitation, respectively. Phosphorylated KSS1 activates both pathways, whereas activated FUS3 activates the mating but suppresses the filamentation pathway. KSS1 a [...] (368 aa)
           
  0.895
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)
           
  0.829
YLR042C
Protein of unknown function; localizes to the cytoplasm; YLL042C is not an essential gene (161 aa)
           
  0.543
MSB2
Mucin family member involved in the Cdc42p- and MAP kinase-dependent filamentous growth signaling pathway; also functions as an osmosensor in parallel to the Sho1p-mediated pathway; potential Cdc28p substrate; Plasma membrane signaling mucin that promotes activation of the MAPK for the filamentous growth pathway. Partially redundant with the SHO1 osmosensing branch for the activation of STE11 (1306 aa)
           
  0.540
TEC1
Transcription factor targeting filamentation genes and Ty1 expression; Ste12p activation of most filamentation gene promoters depends on Tec1p and Tec1p transcriptional activity is dependent on its association with Ste12p; binds to TCS elements upst /.../f filamentation genes, which are regulated by Tec1p/Ste12p/Dig1p complex; competes with Dig2p for binding to Ste12p/Dig1p; positive regulator of chronological life span; TEA/ATTS DNA-binding domain family member; TEC1 is involved in the activation of TY1 and TY1- mediated gene expression. It is not involved in mating or sporulation processes (486 aa)
           
  0.516
STE12
Transcription factor that is activated by a MAPK signaling cascade; activates genes involved in mating or pseudohyphal/invasive growth pathways; cooperates with Tec1p transcription factor to regulate genes specific for invasive growth; Binds to the DNA sequence mediating pheromone induction (called the pheromone response element = PRE) which is found in the upstream control region of several a-, alpha- and haploid- specific genes. Involved in mating of haploids and in pseudohyphae formation in diploids (688 aa)
           
  0.487
ILV2
Acetolactate synthase, catalyses the first common step in isoleucine and valine biosynthesis and is the target of several classes of inhibitors, localizes to the mitochondria; expression of the gene is under general amino acid control (687 aa)
           
  0.472
SVS1
Cell wall and vacuolar protein, required for wild-type resistance to vanadate; Required for vanadate resistance (260 aa)
     
   
  0.464
DIG1
MAP kinase-responsive inhibitor of the Ste12p transcription factor, involved in the regulation of mating-specific genes and the invasive growth pathway; related regulators Dig1p and Dig2p bind to Ste12p; DIG1 and DIG2 are negative regulators of the filamentation and pheromone induced mating program. DIG1 and DIG2 inhibit the transcriptional activity of STE12 by direct protein- protein interaction. DIG1 colocalizes to promoters with STE12 and redistributes with it during induction of filamentation (by butanol) or mating (by pheromone) to program specific genes, but binding of DIG1 to ST [...] (452 aa)
           
  0.441
STE11
Signal transducing MEK kinase involved in pheromone response and pseudohyphal/invasive growth pathways where it phosphorylates Ste7p, and the high osmolarity response pathway, via phosphorylation of Pbs2p; regulated by Ste20p and Ste50p; Serine/threonine protein kinase required for cell-type- specific transcription and signal transduction in yeast. It is thought that it phosphorylates the STE7 protein kinase which itself, phosphorylates the FUS3 and or KSS1 kinases (717 aa)
