STRINGSTRING
ORM1 protein (Saccharomyces cerevisiae) - STRING interaction network
"ORM1" - Evolutionarily conserved protein, similar to Orm2p, required for resistance to agents that induce unfolded protein response 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

LCB2
Component of serine palmitoyltransferase, responsible along with Lcb1p for the first committed step in sphingolipid synthesis, which is the condensation of serine with palmitoyl-CoA to form 3-ketosphinganine; Catalytic subunit of serine palmitoyltransferase (SPT), which catalyzes the committed step in the synthesis of sphingolipids, the condensation of serine with palmitoyl CoA to form the long chain base 3-ketosphinganine (561 aa)

  0.930
YPK1
Serine/threonine protein kinase that phosphorylates and downregulates flippase activator Fpk1p; mutations affect receptor-mediated endocytosis and sphingolipid-mediated and cell integrity signaling pathways; homolog of mammalian kinase SGK; Plays an essential role in the proliferation of yeast cells. Involved in a signaling pathway, required for optimal cell wall integrity, that acts in parallel with the PKC1-SLT2-dependent pathway. Downstream kinase in the sphingolipid-mediated signaling pathway. Its phosphorylation is regulated by the intracellular sphingolipid concentration. Coopera [...] (680 aa)
