STRINGSTRING
SUR1 protein (Saccharomyces cerevisiae) - STRING interaction network
"SUR1" - Probable catalytic subunit of a mannosylinositol phosphorylceramide 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

SUR1Probable catalytic subunit of a mannosylinositol phosphorylceramide (MIPC) synthase, forms a complex with probable regulatory subunit Csg2p; function in sphingolipid biosynthesis is overlapping with that of Csh1p; Involved in the synthesis of mannosyl phosphorylinositol ceramide. Catalyzes the addition of mannosyl to phosphorylinositol ceramide. Suppressor of RVS161 mutation (382 aa)    
Predicted Functional Partners:
CSG2
Endoplasmic reticulum membrane protein, required for mannosylation of inositolphosphorylceramide and for growth at high calcium concentrations; Required for calcium regulation. May regulate calcium accumulation by a non-vacuole organelle. Also regulates the activity of CSH1 and SUR1 during mannosyl phosphorylinositol ceramide synthesis (410 aa)
       
  0.997
AUR1
Phosphatidylinositol-ceramide phosphoinositol transferase (IPC synthase), required for sphingolipid synthesis; can mutate to confer aureobasidin A resistance; Catalytic component of the inositol phosphorylceramide synthase which catalyzes the addition of a phosphorylinositol group onto ceramide to form inositol phosphorylceramide, an essential step in sphingolipid biosynthesis (401 aa)
     
  0.994
IPT1
Inositolphosphotransferase; involved in synthesis of mannose-(inositol-P)2-ceramide (M(IP)2C), the most abundant sphingolipid; can mutate to resistance to the antifungals syringomycin E and DmAMP1 and to K. lactis zymocin; Catalyzes the addition of a phosphorylinositol group onto mannosyl phosphorylinositol ceramide to form mannosyl diphosphorylinositol ceramide (527 aa)
       
  0.992
CCC2
Cu(+2)-transporting P-type ATPase, required for export of copper from the cytosol into an extracytosolic compartment; has similarity to human proteins involved in Menkes and Wilsons diseases; Probably involved in copper transport and in the regulation of cellular copper level. Retrieves copper from the metallochaperone ATX1 and incorporates it into trans-Golgi vesicles (1004 aa)
       
 
  0.955
SCS7
Sphingolipid alpha-hydroxylase, functions in the alpha-hydroxylation of sphingolipid-associated very long chain fatty acids, has both cytochrome b5-like and hydroxylase/desaturase domains, not essential for growth; Ceramide hydroxylase involved in the alpha-hydroxylation of sphingolipid-associated very long chain fatty acids. Hydroxylates the very long chain fatty acid of ceramides at C2 and C3 (384 aa)
       
 
  0.907
SUR2
Sphinganine C4-hydroxylase, catalyses the conversion of sphinganine to phytosphingosine in sphingolipid biosyntheis; Required for hydroxylation of C-4 in the sphingoid moiety of ceramide. Involved in the response to syringomycin (349 aa)
       
 
  0.906
CSH1
Probable catalytic subunit of a mannosylinositol phosphorylceramide (MIPC) synthase, forms a complex with probable regulatory subunit Csg2p; function in sphingolipid biosynthesis is overlapping with that of Sur1p; Involved in the synthesis of mannosyl phosphorylinositol ceramide.

AFT1
Transcription factor involved in iron utilization and homeostasis; binds the consensus site PyPuCACCCPu and activates the expression of target genes in response to changes in iron availability; Probable transcription factor that activates the genes for FRE1, FRE2 and FET3 in response to iron deprivation. Iron could interact directly with AFT1 and inhibits its activity (690 aa)
           
  0.828
RVS161
Amphiphysin-like lipid raft protein; interacts with Rvs167p and regulates polarization of the actin cytoskeleton, endocytosis, cell polarity, cell fusion and viability following starvation or osmotic stress; Component of a cytoskeletal structure that is required for the formation of endocytic vesicles at the plasma membrane level (265 aa)
       
 
  0.795
RVS167
Actin-associated protein with roles in endocytosis and exocytosis; interacts with Rvs161p to regulate actin cytoskeleton, endocytosis, and viability following starvation or osmotic stress; recruited to bud tips by Gyl1p and Gyp5p during polarized gr /.../homolog of mammalian amphiphysin; Component of a cytoskeletal structure that is required for the formation of endocytic vesicles at the plasma membrane level. Could be implicated in cytoskeletal reorganization in response to environmental stresses and could act in the budding site selection mechanism (482 aa)
