STRINGSTRING
PTC1 protein (Saccharomyces cerevisiae) - STRING interaction network
"PTC1" - Type 2C protein phosphatase 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

PTC1Type 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)    
Predicted Functional Partners:
HOG1
Mitogen-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)

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)

NBP2
Protein involved in the HOG (high osmolarity glycerol) pathway, negatively regulates Hog1p by recruitment of phosphatase Ptc1p the Pbs2p-Hog1p complex, found in the nucleus and cytoplasm, contains an SH3 domain that binds Pbs2p; Negatively regulates the high-osmolarity glycerol (HOG) pathway through its negative regulation of the HOG1 kinase activity. Mediates the binding between the PTC1 phosphatase and the PBS2 MAP/ERK kinase (MEK). With PTC1, regulates endoplasmic reticulum inheritance through the cell wall integrity (CWI) MAPK pathway by modulating the MAPK, SLT2 (236 aa)

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)

SLN1
Histidine kinase osmosensor that regulates a MAP kinase cascade; transmembrane protein with an intracellular kinase domain that signals to Ypd1p and Ssk1p, thereby forming a phosphorelay system similar to bacterial two-component regulators; Histidine kinase that acts as a osmosensor at the plasma membrane. Part of the bifurcated SLN1-YPD1-SKN7/SSK1 two-component regulatory system, which controls activity of the HOG1 pathway and gene expression in response to changes in the osmolarity of the extracellular environment. Under normal osmotic conditions, the histidine kinase autophosphoryla [...] (1220 aa)
