STRINGSTRING
STE12 protein (Saccharomyces cerevisiae) - STRING interaction network
"STE12" - Transcription factor that is activated by a MAPK signaling cascade 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

STE12Transcription 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)    
Predicted Functional Partners:
TEC1
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)
     
  0.999
KSS1
Mitogen-activated protein kinase (MAPK) involved in signal transduction pathways that control filamentous growth and pheromone response; the KSS1 gene is nonfunctional in S288C strains and functional in W303 strains; Together with closely related FUS3, KSS1 is the final kinase in the signal transduction cascade regulating activation/repression of the mating and filamentation pathways, induced by pheromone and nitrogen/carbon limitation, respectively. Phosphorylated KSS1 activates both pathways, whereas activated FUS3 activates the mating but suppresses the filamentation pathway. KSS1 a [...] (368 aa)
       
  0.999
DIG1
MAP kinase-responsive inhibitor of the Ste12p transcription factor, involved in the regulation of mating-specific genes and the invasive growth pathway; related regulators Dig1p and Dig2p bind to Ste12p; DIG1 and DIG2 are negative regulators of the filamentation and pheromone induced mating program. DIG1 and DIG2 inhibit the transcriptional activity of STE12 by direct protein- protein interaction. DIG1 colocalizes to promoters with STE12 and redistributes with it during induction of filamentation (by butanol) or mating (by pheromone) to program specific genes, but binding of DIG1 to ST [...] (452 aa)
       
  0.999
FUS3
Mitogen-activated serine/threonine protein kinase involved in mating; phosphoactivated by Ste7p; substrates include Ste12p, Far1p, Bni1p, Sst2p; inhibits invasive growth during mating by phosphorylating Tec1p, promoting its degradation; Together with closely related KSS1, FUS3 is the final kinase in the signal transduction cascade regulating activation/repression of the mating and filamentation pathways, induced by pheromone and nitrogen/carbon limitation, respectively. Phosphorylated FUS3 activates the mating but suppresses the filamentation pathway, whereas activated KSS1 activates b [...] (353 aa)
     
  0.998
MCM1
Transcription factor involved in cell-type-specific transcription and pheromone response; plays a central role in the formation of both repressor and activator complexes; Transcription factor required for the efficient replication of minichromosomes and the transcriptional regulation of early cell cycle genes. Activates transcription of ECB- dependent genes during the G1/M phase. Genes that contain a ECB (early cell box) element in their transcription regulatory region are transcribed only during G1/M phases. Interacts with the alpha- 2 repressor or with the alpha-1 activator thereby r [...] (286 aa)
       
  0.997
DIG2
MAP kinase-responsive inhibitor of the Ste12p transcription factor, involved in the regulation of mating-specific genes and the invasive growth pathway; related regulators Dig1p and Dig2p bind to Ste12p; DIG2 and DIG1 are negative regulators of the filamentation and pheromone induced mating program. DIG1 and DIG2 inhibit the transcriptional activity of STE12 by direct protein- protein interaction. DIG2 binds to the DNA binding domain (DBD) of STE12 and thus inhibits transcription when overexpressed (323 aa)
       
  0.996
MSS11
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)
       
  0.981
STE11
Signal transducing MEK kinase involved in pheromone response and pseudohyphal/invasive growth pathways where it phosphorylates Ste7p, and the high osmolarity response pathway, via phosphorylation of Pbs2p; regulated by Ste20p and Ste50p; Serine/threonine protein kinase required for cell-type- specific transcription and signal transduction in yeast. It is thought that it phosphorylates the STE7 protein kinase which itself, phosphorylates the FUS3 and or KSS1 kinases (717 aa)
     
  0.974
GPA1
GTP-binding alpha subunit of the heterotrimeric G protein that couples to pheromone receptors; negatively regulates the mating pathway by sequestering G(beta)gamma and by triggering an adaptive response; activates Vps34p at the endosome; Alpha subunit of the heterotrimeric guanine nucleotide- binding protein (G protein) that mediates mating pheromone signal transduction. Binding of alpha-factor or a-factor to its cognate transmembrane receptor STE2 and STE3, respectively, allows the receptor to serve as a guanine nucleotide exchange factor (GEF) on GPA1. The exchange of GDP for GTP on [...] (472 aa)
     
  0.972
STE7
Signal transducing MAP kinase kinase involved in pheromone response, where it phosphorylates Fus3p, and in the pseudohyphal/invasive growth pathway, through phosphorylation of Kss1p; phosphorylated by Ste11p, degraded by ubiquitin pathway; Serine/threonine protein kinase required for cell-type- specific transcription and signal transduction in yeast. It is thought that it is phosphorylated by the ste11 protein kinase and that it can phosphorylate the FUS3 and or KSS1 kinases (515 aa)
