STRINGSTRING
SFP1 protein (Saccharomyces cerevisiae) - STRING interaction network
"SFP1" - Transcription factor that controls expression of ribosome biogenesis genes in response to nutrients and stress, regulates G2/M transitions during mitotic cell cycle and DNA-damage response, modulates cell size 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

SFP1Transcription factor that controls expression of ribosome biogenesis genes in response to nutrients and stress, regulates G2/M transitions during mitotic cell cycle and DNA-damage response, modulates cell size; regulated by TORC1 and Mrs6p; can form /.../ISP+] prion; Transcription factor that regulates ribosomal protein (RP) and ribosome biogenesis (Ribi) gene expression in response to nutrients and stress. Promotes RP gene expression under optimal growth conditions. Leaves the nucleus upon environmental challenges, resulting in a down-regulation of RP gene transcription. The effect of [...] (683 aa)    
Predicted Functional Partners:
MRS6
Rab escort protein, forms a complex with the Ras-like small GTPase Ypt1p that is required for the prenylation of Ypt1p by protein geranylgeranyltransferase type II (Bet2p-Bet4p); sequence similarity to mammalian choroideraemia gene; Substrate-binding subunit (component A) of the Rab geranylgeranyltransferase (GGTase) complex. Binds unprenylated Rab proteins and presents the substrate peptide to the catalytic component B. The component A is thought to be regenerated by transferring its prenylated Rab back to the donor membrane (603 aa)

SCH9
Protein kinase involved in transcriptional activation of osmostress-responsive genes; regulates G1 progression, cAPK activity, nitrogen activation of the FGM pathway; involved in life span regulation; homologous to mammalian Akt/PKB; Protein kinase that is part of growth control pathway which is at least partially redundant with the cAMP pathway. Regulates both BCY1 phosphorylation and MPK1 activity (PubMed-20702584). Regulates ribosome biogenesis, translation initiation, and entry into stationary phase in a TORC1-dependent manner (PubMed-17560372) (824 aa)
     
 
  0.894
IFH1
Coactivator that regulates transcription of ribosomal protein (RP) genes; recruited to RP gene promoters during optimal growth conditions via Fhl1p; subunit of CURI, a complex that coordinates RP production and pre-rRNA processing; Controls the pre-rRNA processing machinery in conjunction with FHL1. Could convert FHL1 from a repressor to an activator (1085 aa)
     
   
  0.837
STB3
Ribosomal RNA processing element (RRPE)-binding protein involved in the glucose-induced transition from quiescence to growth; restricted to nucleus in quiescent cells, released into cytoplasm after glucose repletion; binds Sin3p (513 aa)
       
 
  0.809
TOR1
PIK-related protein kinase and rapamycin target; subunit of TORC1, a complex that controls growth in response to nutrients by regulating translation, transcription, ribosome biogenesis, nutrient transport and autophagy; involved in meiosis; Phosphatidylinositol 3-kinase homolog, component of TORC1, which regulates multiple cellular processes to control cell growth in response to environmental signals. Nutrient limitation and environmental stress signals cause inactivation of TORC1. Active TORC1 positively controls ribosome biogenesis via control of rRNA, ribosomal protein and tRNA gene [...] (2470 aa)
       
 
  0.801
BAR1
Aspartyl protease secreted into the periplasmic space of mating type a cells, helps cells find mating partners, cleaves and inactivates alpha factor allowing cells to recover from alpha-factor-induced cell cycle arrest; This protein called "barrier activity" is excreted by yeast cells mating type a. It is probably a protease that cleaves alpha-factor and thus acts as an antagonist of this mating pheromone and establishes optimal pheromone concentration for conjugation (587 aa)
       
      0.789
RAS2
GTP-binding protein that regulates the nitrogen starvation response, sporulation, and filamentous growth; farnesylation and palmitoylation required for activity and localization to plasma membrane; homolog of mammalian Ras proto-oncogenes; The S.cerevisiae Ras proteins modulate the activity of the adenylate cyclase catalytic subunit and therefore affect the biosynthesis of cyclic-AMP (322 aa)
       
 
  0.730
CLN3
G1 cyclin involved in cell cycle progression; activates Cdc28p kinase to promote the G1 to S phase transition; plays a role in regulating transcription of the other G1 cyclins, CLN1 and CLN2; regulated by phosphorylation and proteolysis; Essential for the control of the cell cycle at the G1/S (start) transition. CLN3 may be an upstream activator of the G1 cyclins which directly catalyze start (580 aa)
     
 
  0.711
FHL1
Regulator of ribosomal protein transcription; has forkhead associated domain that binds phosphorylated proteins; also has forkhead DNA-binding domain but does not bind DNA in vitro; suppresses RNA pol III and splicing factor prp4 mutants; Controls the pre-rRNA processing machinery in conjunction with IFH1. Presumably acts as a transcriptional regulator of genes specifically involved in that process. IFH1 convert FHL1 from a repressor to an activator (936 aa)

LST8
Protein required for the transport of amino acid permease Gap1p from the Golgi to the cell surface; component of the TOR signaling pathway; associates with both Tor1p and Tor2p; contains a WD-repeat; Essential component of both TORC1 and TORC2. TORC1 regulates multiple cellular processes to control cell growth in response to environmental signals. Nutrient limitation and environmental stress signals cause inactivation of TORC1. Active TORC1 positively controls ribosome biogenesis via control of rRNA, ribosomal protein and tRNA gene expression, and rRNA processing. TORC1 positively cont [...] (303 aa)
