STRINGSTRING
KEI1 protein (Saccharomyces cerevisiae) - STRING interaction network
"KEI1" - Component of inositol 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

KEI1Component of inositol phosphorylceramide (IPC) synthase; forms a complex with Aur1p and regulates its activity; required for IPC synthase complex localization to the Golgi; post-translationally processed by Kex2p; KEI1 is an essential gene; Regulatory component of the inositol phosphorylceramide (ICP) synthase which catalyzes the addition of a phosphorylinositol group onto ceramide to form inositol phosphorylceramide, an essential step in sphingolipid biosynthesis. Helps the medial Golgi localization of IPC synthase in a COPI vesicle-dependent manner (221 aa)    
Predicted Functional Partners:
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)
       
  0.963
KRE2
Alpha1,2-mannosyltransferase of the Golgi involved in protein mannosylation; Required for the attachment of the third mannose residue of O-linked saccharides (442 aa)
       
 
  0.602
SEC21
Gamma subunit of coatomer, a heptameric protein complex that together with Arf1p forms the COPI coat; involved in ER to Golgi transport of selective cargo; The coatomer is a cytosolic protein complex that binds to dilysine motifs and reversibly associates with Golgi non- clathrin-coated vesicles, which further mediate biosynthetic protein transport from the ER, via the Golgi up to the trans Golgi network. Coatomer complex is required for budding from Golgi membranes, and is essential for the retrograde Golgi-to-ER transport of dilysine-tagged proteins (935 aa)
       
 
  0.599
COP1
Alpha subunit of COPI vesicle coatomer complex, which surrounds transport vesicles in the early secretory pathway; The coatomer is a cytosolic protein complex that binds to dilysine motifs and reversibly associates with Golgi non- clathrin-coated vesicles, which further mediate biosynthetic protein transport from the ER, via the Golgi up to the trans Golgi network. Coatomer complex is required for budding from Golgi membranes, and is essential for the retrograde Golgi-to-ER transport of dilysine-tagged proteins (1201 aa)
       
      0.577
CWH43
Putative sensor/transporter protein involved in cell wall biogenesis; contains 14-16 transmembrane segments and several putative glycosylation and phosphorylation sites; null mutation is synthetically lethal with pkc1 deletion; Involved in the maintenance of cell wall integrity. Required for the replacement of the diacylglycerol moiety by ceramides during GPI-anchor maturation (953 aa)
           
  0.544
LDS2
Protein of unknown function; green fluorescent protein (GFP)-fusion protein localizes to the cytoplasm in a punctate pattern; Involved in spore wall assembly (356 aa)

TDA5
Putative protein of unknown function; detected in highly purified mitochondria in high-throughput studies; proposed to be involved in resistance to mechlorethamine and streptozotocin; null mutant sensitive to expression of top1-T722A allele; Involved in the resistance to DNA-damaging agents (326 aa)
           
  0.487
EFM5
Putative protein of unknown function with similarity to methyltransferase family members; green fluorescent protein (GFP)-fusion protein localizes to the cytoplasm; required for replication of Brome mosaic virus in S. cerevisiae; S-adenosyl-L-methionine-dependent protein-lysine N- methyltransferase that trimethylates elongation factor 1-alpha (TEF1 and TEF2) at ’Lys-79’ (PubMed-25446118). Required for replication of Brome mosaic virus (BMV) (PubMed-14671320) (248 aa)
