STRINGSTRING
PTP2 protein (Saccharomyces cerevisiae) - STRING interaction network
"PTP2" - Phosphotyrosine-specific protein phosphatase involved in the inactivation of mitogen-activated protein kinase 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

PTP2Phosphotyrosine-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)
