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:
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 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

Score
NSDHLSterol-4-alpha-carboxylate 3-dehydrogenase, decarboxylating; Involved in the sequential removal of two C-4 methyl groups in post-squalene cholesterol biosynthesis; Short chain dehydrogenase/reductase superfamily (373 aa)    
Predicted Functional Partners:
MSMO1
Methylsterol monooxygenase 1; Catalyzes the first step in the removal of the two C-4 methyl groups of 4,4-dimethylzymosterol; Belongs to the sterol desaturase family
  
 0.999
LSS
Lanosterol synthase; Catalyzes the cyclization of (S)-2,3 oxidosqualene to lanosterol, a reaction that forms the sterol nucleus. Through the production of lanosterol may regulate lens protein aggregation and increase transparency; Belongs to the terpene cyclase/mutase family
  
 
 0.998
CYP51A1
Lanosterol 14-alpha demethylase; Catalyzes C14-demethylation of lanosterol; it transforms lanosterol into 4,4'-dimethyl cholesta-8,14,24-triene-3-beta-ol; Cytochrome P450 family 51
   
 
 0.997
HSD17B7
3-keto-steroid reductase; Responsible for the reduction of the keto group on the C-3 of sterols; Short chain dehydrogenase/reductase superfamily
   
 0.997
SQLE
Squalene monooxygenase; Catalyzes the first oxygenation step in sterol biosynthesis and is suggested to be one of the rate-limiting enzymes in this pathway; Belongs to the squalene monooxygenase family
   
 
 0.995
FDFT1
Squalene synthase; Farnesyl-diphosphate farnesyltransferase 1
  
 
 0.994
SC5D
Lathosterol oxidase; Catalyzes a dehydrogenation to introduce C5-6 double bond into lathosterol; Belongs to the sterol desaturase family
  
 
 0.975
IDI1
Isopentenyl-diphosphate Delta-isomerase 1; Catalyzes the 1,3-allylic rearrangement of the homoallylic substrate isopentenyl (IPP) to its highly electrophilic allylic isomer, dimethylallyl diphosphate (DMAPP)
   
  
 0.975
HMGCS1
Hydroxymethylglutaryl-CoA synthase, cytoplasmic; This enzyme condenses acetyl-CoA with acetoacetyl-CoA to form HMG-CoA, which is the substrate for HMG-CoA reductase
  
 
 0.972
TM7SF2
Delta(14)-sterol reductase; Involved in the conversion of lanosterol to cholesterol
  
 
 0.967
