STRINGSTRING
YDC1 protein (Saccharomyces cerevisiae) - STRING interaction network
"YDC1" - Alkaline dihydroceramidase, involved in sphingolipid metabolism 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

YDC1Alkaline dihydroceramidase, involved in sphingolipid metabolism; preferentially hydrolyzes dihydroceramide to a free fatty acid and dihydrosphingosine; has a minor reverse activity; Catalyzes the conversion of dihydroceramide and also phytoceramide to dihydrosphingosine or phytosphingosine. Prefers dihydroceramide. Very low reverse hydrolysis activity, catalyzing synthesis of dihydroceramide from fatty acid and dihydrosphingosine. Is not responsible for the breakdown of unsaturated ceramide. May play a role in heat stress response (317 aa)
