STRINGSTRING
STRING protein interaction network
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:
a 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 to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

cyp125Probable cytochrome P450 125 Cyp125; Involved in the utilization of cholesterol as the sole carbon and energy source by degrading the side chain during infection. Primarily catalyzes the sequential oxidation of the terminal methyl of cholest-4-en-3-one into (25S)-26- hydroxycholest-4-en-3-one (alcohol), (25S)-26-oxocholest-4-en-3-one (aldehyde), to finally yield the carboxylic acid (25S)-3-oxocholest-4- en-26-oate. Also able to sequentially oxidize cholesterol itself, not only cholest-4-en- 3-one. Belongs to the cytochrome P450 family. (433 aa)    
Predicted Functional Partners:
