MSN1 protein (Saccharomyces cerevisiae) - STRING interaction network
"MSN1" - Transcriptional activator involved in regulation of invertase and glucoamylase expression, invasive growth and pseudohyphal differentiation, iron uptake, chromium accumulation, and response to osmotic stress in Saccharomyces cerevisiae
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 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
protein homology

Gene Fusion
MSN1Transcriptional activator involved in regulation of invertase and glucoamylase expression, invasive growth and pseudohyphal differentiation, iron uptake, chromium accumulation, and response to osmotic stress; localizes to the nucleus; May function as a transcriptional activator. Increased dosage of MSN1 restores invertase expression in yeast mutants defective in the SNF1 protein kinase, and msn1 disruption reduced derepression of invertase in the wild-type. May affect SUC2 expression. Expression of MSN1 enhances growth in iron-limiting conditions (382 aa)    
Predicted Functional Partners:
Transcription factor involved in regulation of invasive growth and starch degradation; controls the activation of MUC1 and STA2 in response to nutritional signals; Transcription factor that regulates pseudohyphal differentiation, invasive growth, floculation, adhesion and starch metabolism in response to nutrient availability (758 aa)
Transcription factor required for flocculation, diploid filamentous growth, and haploid invasive growth; genome reference strain S288C and most laboratory strains have a mutation in this gene; Required for diploid filamentous growth, haploid invasive growth and flocculation. Putative transcriptional activator of FLO1 (799 aa)
Ammonium permease involved in regulation of pseudohyphal growth; belongs to a ubiquitous family of cytoplasmic membrane proteins that transport only ammonium (NH4+); expression is under the nitrogen catabolite repression regulation; Transporter for ammonium (both charged and uncharged NH3 and NH4) to use as a nitrogen source. The affinity of MEP2 is about twenty times higher than that of MEP1. MEP3 has the lowest affinity. Under ammonium limitation acts as an ammonium sensor, generating a signal that leads to pseudohyphal growth (499 aa)
Histone H2B, core histone protein required for chromatin assembly and chromosome function; nearly identical to HTB2; Rad6p-Bre1p-Lge1p mediated ubiquitination regulates transcriptional activation, meiotic DSB formation and H3 methylation; Core component of nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translat [...] (131 aa)
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)
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)
AMP-activated serine/threonine protein kinase found in a complex containing Snf4p and members of the Sip1p/Sip2p/Gal83p family; required for transcription of glucose-repressed genes, thermotolerance, sporulation, and peroxisome biogenesis; Essential for release from glucose repression. It interacts and has functional relationship to the regulatory protein SNF4. Could phosphorylate CAT8. Phosphorylates histone H3 to form H3S10ph, which promotes H3K14ac formation, and which is required for transcriptional activation through TBP recruitment to the promoters (633 aa)
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)
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)
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)
