STRINGSTRING
WHI2 protein (Saccharomyces cerevisiae) - STRING interaction network
"WHI2" - Protein required, with binding partner Psr1p, for full activation of the general stress response, possibly through Msn2p dephosphorylation 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

WHI2Protein required, with binding partner Psr1p, for full activation of the general stress response, possibly through Msn2p dephosphorylation; regulates growth during the diauxic shift; negative regulator of G1 cyclin expression; Plays a role in the coordination of growth and proliferation. Required for entry into G0 phase under conditions of carbon limitation. Involved in the general stress response; acts together with PSR1 to activate stress response element (STRE)-mediated gene expression, possibly through dephosphorylation of MSN2 (486 aa)    
Predicted Functional Partners:
PSR1
Plasma membrane associated protein phosphatase involved in the general stress response; required along with binding partner Whi2p for full activation of STRE-mediated gene expression, possibly through dephosphorylation of Msn2p; Has phosphatase activity in vitro. Involved in the response to sodium and lithium ion stress (but not to potassium or sorbitol stress) by inducing transcription of the sodium pump ENA1/PMR2. Acts through a calcineurin-independent pathway and is functionally redundant with PSR2. Also involved in the general stress response; acts together with WHI2 to activate st [...] (427 aa)

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.).
