STRINGSTRING
HOG1 protein (Saccharomyces cerevisiae) - STRING interaction network
"HOG1" - Mitogen-activated protein kinase involved in osmoregulation 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

HOG1Mitogen-activated protein kinase involved in osmoregulation; acts via three independent osmosensors; mitophagy-specific regulator; mediates the recruitment and activation of RNA Pol II at Hot1p-dependent promoters; localization regulated by Ptp2p an /.../p; Mitogen-activated protein kinase involved in a signal transduction pathway that is activated by changes in the osmolarity of the extracellular environment. Controls osmotic regulation of transcription via the stress response element (STRE) in promoters of target genes. Upon osmotic shock, associates with the SKO1-SSN6-TUP1 complex, [...] (435 aa)    
Predicted Functional Partners:
SKO1
Basic leucine zipper transcription factor of the ATF/CREB family; forms a complex with Tup1p and Cyc8p to both activate and repress transcription; cytosolic and nuclear protein involved in osmotic and oxidative stress responses; Binds to the CRE motif 5’-TGACGTCA-3’ and acts as a repressor of transcription of the SUC2 gene and most probably other genes (647 aa)
       
  0.999
PBS2
MAP kinase kinase of the HOG signaling pathway; activated under severe osmotic stress; mitophagy-specific regulator; plays a role in regulating Ty1 transposition; Kinase involved in a signal transduction pathway that is activated by changes in the osmolarity of the extracellular environment. Seems to phosphorylate HOG1 on a tyrosine residue (668 aa)
     
0.998
PTP2
Phosphotyrosine-specific protein phosphatase involved in the inactivation of mitogen-activated protein kinase (MAPK) during osmolarity sensing; dephosporylates Hog1p MAPK and regulates its localization; localized to the nucleus; Major phosphatase responsible with PTP3 for tyrosine dephosphorylation of MAP kinase HOG1 to inactivate its activity. May also be involved in the regulation of MAP kinase FUS3. May be implicated in the ubiquitin-mediated protein degradation (750 aa)
       
  0.998
PTP3
Phosphotyrosine-specific protein phosphatase involved in the inactivation of mitogen-activated protein kinase (MAPK) during osmolarity sensing; dephosporylates Hog1p MAPK and regulates its localization; localized to the cytoplasm; Major phosphatase responsible for tyrosine dephosphorylation of MAP kinases FUS3 and HOG1 to inactivate their activity; it also has important roles, along with MSG5, in the inactivation of FUS3 following pheromone stimulation (928 aa)
       
  0.997
SMP1
MADS-box transcription factor involved in osmotic stress response; SMP1 has a paralog, RLM1, that arose from the whole genome duplication; Transcription factor that controls part of the HOG1- mediated osmostress responses. Binds to the DNA sequence 5’- ACTACTA[TA](4)TAG-3’. Does not appear to function in the MPK1 pathway (452 aa)
     
  0.996
RCK2
Protein kinase involved in the response to oxidative and osmotic stress; identified as suppressor of S. pombe cell cycle checkpoint mutations; similar to CaM (calmodulin) kinases; Serine/threonine-protein kinase involved in a signal transduction pathway that is activated by changes in the osmolarity of the extracellular environment (610 aa)
     
0.994
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)
     
  0.992
PTC1
Type 2C protein phosphatase (PP2C); dephosphorylates Hog1p, inactivating osmosensing MAPK cascade; involved in Fus3p activation during pheromone response; deletion affects precursor tRNA splicing, mitochondrial inheritance, and sporulation; It has a serine and a weak tyrosine phosphatase activity with ratios of serine to tyrosine phosphatase activity as high as 200-1. It is essential for growth or germination at 37 degrees Celsius. May have a role in the heat shock response. Involved in tRNA splicing and cell separation (281 aa)
       
  0.992
MSN2
Transcriptional activator related to Msn4p; activated in stress conditions, which results in translocation from the cytoplasm to the nucleus; binds DNA at stress response elements of responsive genes, inducing gene expression; Positive transcriptional factor that acts as a component of the stress responsive system. Recognizes and binds to the stress response element (STRE) which is involved in the response to various forms of stress (heat, oxidative, osmotic, etc.). Involved in the regulation of the CTT1, DDR2, HSP12 genes. May be regulated via WHI2-PSR1 complex phosphatase activity (704 aa)

SHO1
Transmembrane osmosensor involved in activation of the Cdc42p- and MAP kinase-dependent filamentous growth pathway and the high-osmolarity glycerol response pathway; phosphorylated by Hog1p; interacts with Pbs2p, Msb2p, Hkr1p, and Ste11p; Plasma membrane osmosensor that activates the high osmolarity glycerol (HOG) MAPK signaling pathway in response to high osmolarity. Detects changes in external osmolarity and activates PBS2 through the stimulation of STE11 and targets PBS2 to the plasma membrane. PBS2 activation leads to changes in glycerol production that helps to balance the intrace [...] (367 aa)
