STRINGSTRING
SNF4 protein (Saccharomyces cerevisiae) - STRING interaction network
"SNF4" - Activating gamma subunit of the AMP-activated Snf1p kinase complex (contains Snf1p and a Sip1p/Sip2p/Gal83p family member) 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

SNF4Activating gamma subunit of the AMP-activated Snf1p kinase complex (contains Snf1p and a Sip1p/Sip2p/Gal83p family member); activates glucose-repressed genes, represses glucose-induced genes; role in sporulation, and peroxisome biogenesis; Adenine nucleotides-binding subunit gamma of AMP- activated protein kinase (AMPK), an energy sensor protein kinase that plays a key role in regulating cellular energy metabolism. In response to reduction of intracellular ATP levels, AMPK activates energy-producing pathways and inhibits energy-consuming processes- inhibits protein, carbohydrate and li [...] (322 aa)    
Predicted Functional Partners:
SNF1
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)

SIP2
One of three beta subunits of the Snf1 serine/threonine protein kinase complex involved in the response to glucose starvation; null mutants exhibit accelerated aging; N-myristoylprotein localized to the cytoplasm and the plasma membrane; Beta subunit of the SNF1 kinase complex, which is required for transcriptional, metabolic, and developmental adaptations in response to glucose limitation. Has a structural role, mediating heterotrimer formation, and a regulatory role, defining carbon source-regulated subcellular location and substrate specificity of the SNF1 kinase complex. Involved i [...] (415 aa)

GAL83
One of three possible beta-subunits of the Snf1 kinase complex, allows nuclear localization of the Snf1 kinase complex in the presence of a nonfermentable carbon source; contains glycogen-binding domain; Beta subunit of the SNF1 kinase complex, which is required for transcriptional, metabolic, and developmental adaptations in response to glucose limitation. Has a structural role, mediating heterotrimer formation, and a regulatory role, defining carbon source-regulated subcellular location and substrate specificity of the SNF1 kinase complex. Promotes the relocalization of the SNF1 kina [...] (417 aa)

GUA1
GMP synthase; highly conserved enzyme that catalyzes the second step in the biosynthesis of GMP from inosine 5’-phosphate (IMP); transcription is not subject to regulation by guanine but is negatively regulated by nutrient starvation; reduction-of-f /.../n mutation gua1-G388D causes changes in cellular guanine nucleotide pools, defects in general protein synthesis, and impaired translation of GCN4 mRNA (525 aa)
   
  0.999
SIP1
Alternate beta-subunit of the Snf1p kinase complex, may confer substrate specificity; vacuolar protein containing KIS (Kinase-Interacting Sequence) and ASC (Association with Snf1 kinase Complex) domains involved in protein interactions; Beta subunit of the SNF1 kinase complex, which is required for transcriptional, metabolic, and developmental adaptations in response to glucose limitation. Has a structural role, mediating heterotrimer formation, and a regulatory role, defining carbon source-regulated subcellular location and substrate specificity of the SNF1 kinase complex. Promotes th [...] (815 aa)

YLR126C
Putative protein of unknown function with similarity to glutamine amidotransferase proteins; has Aft1p-binding motif in the promoter; may be involved in copper and iron homeostasis; YLR126C is not an essential protein; May have a role in copper and iron homeostasis (251 aa)

SAK1
Upstream serine/threonine kinase for the SNF1 complex; partially redundant with Elm1p and Tos3p; members of this family have functional orthology with LKB1, a mammalian kinase associated with Peutz-Jeghers cancer-susceptibility syndrome; Serine/threonine-protein kinase that phosphorylates SNF1, the catalytic subunit of the SNF1 kinase complex. Acts as an activator of the SNF1 kinase complex and controls its nuclear localization upon glucose and nitrogen depletion. Also required for SNF1 kinase activation under other stress conditions like alkaline pH or presence of cadmium (1142 aa)

HFA1
Mitochondrial acetyl-coenzyme A carboxylase, catalyzes the production of malonyl-CoA in mitochondrial fatty acid biosynthesis; Catalyzes the rate-limiting reaction in the mitochondrial fatty acid synthesis (FAS) type II pathway. Responsible for the production of the mitochondrial malonyl-CoA, used for the biosynthesis of the cofactor lipoic acid. This protein carries three functions- biotin carboxyl carrier protein, biotin carboxylase, and carboxyltransferase (2123 aa)

TOS3
Protein kinase, related to and functionally redundant with Elm1p and Sak1p for the phosphorylation and activation of Snf1p; functionally orthologous to LKB1, a mammalian kinase associated with Peutz-Jeghers cancer-susceptibility syndrome; One of the three SNF1 protein kinases (with SAK1 and ELM1) which are required for growth on nonfermentable carbon sources and nonpreferred sugars and for response to environmental stress.
