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

pi4kbPhosphatidylinositol 4-kinase beta; Phosphorylates phosphatidylinositol (PI) in the first committed step in the production of the second messenger inositol- 1,4,5,-trisphosphate (PIP). (835 aa)    
Predicted Functional Partners:
pi4k2a
Phosphatidylinositol 4-kinase type 2-alpha; Membrane-bound phosphatidylinositol-4 kinase (PI4-kinase) that catalyzes the phosphorylation of phosphatidylinositol (PI) to phosphatidylinositol 4-phosphate (PI4P), a lipid that plays important roles in endocytosis, Golgi function, protein sorting and membrane trafficking. Besides, phosphorylation of phosphatidylinositol (PI) to phosphatidylinositol 4-phosphate (PI4P) is the first committed step in the generation of phosphatidylinositol 4,5-bisphosphate (PIP2), a precursor of the second messenger inositol 1,4,5-trisphosphate (InsP3).
   
 0.992
cdipt
CDP-diacylglycerol--inositol 3-phosphatidyltransferase.
     
 0.989
arf1
ADP-ribosylation factor 1; Belongs to the small GTPase superfamily. Arf family.
    
 0.970
pikfyve
Phosphatidylinositol phosphate 5-kinase type III isoform d.
   
 
 0.967
pi4kaa
Phosphatidylinositol 4-kinase, catalytic, alpha a; Belongs to the PI3/PI4-kinase family.
    
0.963
inpp5b
Inositol polyphosphate-5-phosphatase B.
   
 
 0.961
pi4k2b
Phosphatidylinositol 4-kinase type 2-beta; Contributes to the overall PI4-kinase activity of the cell. The phosphorylation of phosphatidylinositol (PI) to PI4P is the first committed step in the generation of phosphatidylinositol 4,5- bisphosphate (PIP2), a precursor of the second messenger inositol 1,4,5-trisphosphate (InsP3) (By similarity).
   
 0.956
ocrl
OCRL inositol polyphosphate-5-phosphatase.
   
 
 0.953

Neuronal calcium sensor 1a.
    
 
 0.953
pik3c3
Phosphatidylinositol 3-kinase catalytic subunit type 3.
     
0.944
