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

Sac1Sac1 phosphatase (Sac1) encodes a lipid phosphatase that dephosphorylates phosphatidylinositol 4-phosphate to generate phosphatidylinositol. It is involved in dorsal closure, Hedgehog signaling and axon guidance. (592 aa)    
Predicted Functional Partners:
Pi4KIIIalpha
Phosphatidylinositol 4-kinase III alpha (PI4KIIIalpha) encodes a lipid kinase that synthesizes phosphatidylinositol 4-phosphate from phosphatidylinositol. Its roles include localization of plasma membrane-associated cytoskeletal and membrane trafficking proteins, Hippo signaling regulation and polarization of developing oocytes; Belongs to the PI3/PI4-kinase family.

Ocrl
Oculocerebrorenal syndrome of Lowe (Ocrl) encodes an inositol polyphosphate 5-phosphatase that regulates PtdIns(4,5)P2 homeostasis by dephosphorylating PtdIns(4,5)P2 on endocytic compartments. In vitro experiments also suggest a role of the product of Ocrl during cytokinesis.

fwd
Four wheel drive (fwd) encodes a Golgi-localized lipid kinase that synthesizes phosphatidylinositol 4-phosphate from phosphatidylinositol. It is involved in spermatocyte cytokinesis and male fertility; Belongs to the PI3/PI4-kinase family.
    
 0.987
Pi4KIIalpha
Pi4KIIalpha, isoform A; Pi4KIIalpha (Pi4KIIalpha) encodes a lipid kinase that synthesizes phosphatidylinositol 4-phosphate from phosphatidylinositol. It contributes to membrane trafficking in the larval salivary gland.

INPP5E
Inositol polyphosphate 5-phosphatase E; Converts phosphatidylinositol 3,4,5-trisphosphate (PtdIns 3,4,5-P3) to PtdIns-P2, and phosphatidylinositol 4,5-bisphosphate (PtdIns 4,5-P2) to phosphatidylinositol 4-phosphate (PI-4-P). By controlling the phosphoinositide composition of the cilia membrane of auditory receptor neurons, regulates the cilia localization of ktub and consequently the transient receptor potential channels iav and nompC. Belongs to the inositol 1,4,5-trisphosphate 5-phosphatase type IV family.

sau
Golgi phosphoprotein 3 homolog sauron; Phosphatidylinositol-4-phosphate-binding protein that links Golgi membranes to the cytoskeleton and may participate in the tensile force required for vesicle budding from the Golgi. Thereby, may play a role in Golgi membrane trafficking and could indirectly give its flattened shape to the Golgi apparatus (By similarity). May also bind to the coatomer to regulate Golgi membrane trafficking. May play a role in anterograde transport from the Golgi to the plasma membrane and regulate secretion (By similarity). Also involved in the control of the local [...]

CG3530
GH09546p; Metal ion binding; phosphatidylinositol-3-phosphatase activity; protein tyrosine phosphatase activity; phosphatidylinositol-3,5-bisphosphate 3-phosphatase activity. It is involved in the biological process described with: phosphatidylinositol dephosphorylation; mitotic cell cycle; regulation of autophagy.
     
 0.961
sktl
Skittles, isoform A; Skittles (sktl) encodes the major Phosphatidylinositol 4-Phosphate-5 kinase (PI4P5K), catalysing the formation of phosphoinositol-4,5-bisphosphate (PIP4,5). The sktl product is involved in many cellular processes involving (PIP4,5), such as endocytosis. It plays an important role in cell polarity by controlling the localization of the product encoded by baz.

mtm
Myotubularin, isoform A; Myotubularin (mtm) encodes a phosphatidylinositol-3-phosphatase that, together with the products of Sbf and Rab21, regulates macrophage protrusion formation. It is involved in cortical actin cytoskeleton organization, chromosome segregation and endocytic recycling.
   
 
 0.953
Synj
Synaptojanin, isoform A; Synaptojanin (Synj) encodes a synaptic Phosphoinositide phosphate (PtdInsP) phosphatase that catalyzes the hydrolysis of phosphate groups from phosphorylated inositols. It is recruited or stabilized by the product of EndoA to endocytic membranes, and it catalyzes dephosphorylation reactions implicated in the uncoating of nascent endocytic vesicles. When the product of Synj dephosphorylates phosphoinositides on nascent vesicles, endocytic adaptors with affinity for these lipids will leave the membrane to uncoat the vesicle.
