"STARD3" - StAR-related lipid transfer protein 3 in Homo sapiens
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

STARD3StAR-related lipid transfer protein 3; Sterol-binding protein that mediates cholesterol transport from the endoplasmic reticulum to endosomes. Creates contact site between the endoplasmic reticulum and late endosomes- localizes to late endosome membranes and contacts the endoplasmic reticulum via interaction with VAPA and VAPB. Acts as a lipid transfer protein that redirects sterol to the endosome at the expense of the cell membrane and favors membrane formation inside endosomes. May also mediate cholesterol transport between other membranes, such as mitochondria membrane or cell membr [...] (445 aa)    
Predicted Functional Partners:
STARD4
StAR-related lipid transfer protein 4; May be involved in the intracellular transport of sterols or other lipids. May bind cholesterol or other sterols (By similarity); StAR related lipid transfer domain containing (205 aa)
         
0.923
STARD6
StAR-related lipid transfer protein 6; May be involved in the intracellular transport of sterols or other lipids. May bind cholesterol or other sterols (By similarity); StAR related lipid transfer domain containing (220 aa)
         
0.922
STAR
Steroidogenic acute regulatory protein, mitochondrial; Plays a key role in steroid hormone synthesis by enhancing the metabolism of cholesterol into pregnenolone. Mediates the transfer of cholesterol from the outer mitochondrial membrane to the inner mitochondrial membrane where it is cleaved to pregnenolone; StAR related lipid transfer domain containing (285 aa)
         
0.913
STARD3NL
STARD3 N-terminal-like protein; Tethering protein that creates contact site between the endoplasmic reticulum and late endosomes- localizes to late endosome membranes and contacts the endoplasmic reticulum via interaction with VAPA and VAPB; Belongs to the STARD3 family (234 aa)
         
0.904
PGAP3
Post-GPI attachment to proteins factor 3; Involved in the lipid remodeling steps of GPI-anchor maturation. Lipid remodeling steps consist in the generation of 2 saturated fatty chains at the sn-2 position of GPI-anchors proteins. Required for phospholipase A2 activity that removes an acyl-chain at the sn-2 position of GPI-anchors during the remodeling of GPI (Probable); Belongs to the PGAP3 family (320 aa)
     
   
  0.842
NPC2
Epididymal secretory protein E1; Intracellular cholesterol transporter which acts in concert with NPC1 and plays an important role in the egress of cholesterol from the endosomal/lysosomal compartment. Both NPC1 and NPC2 function as the cellular ’tag team duo’ (TTD) to catalyze the mobilization of cholesterol within the multivesicular environment of the late endosome (LE) to effect egress through the limiting bilayer of the LE. NPC2 binds unesterified cholesterol that has been released from LDLs in the lumen of the late endosomes/lysosomes and transfers it to the cholesterol-binding po [...] (151 aa)
     
   
  0.815
PCTP
Phosphatidylcholine transfer protein; Catalyzes the transfer of phosphatidylcholine between membranes. Binds a single lipid molecule; StAR related lipid transfer domain containing (214 aa)
     
   
  0.808
MIEN1
Migration and invasion enhancer 1; Increases cell migration by inducing filopodia formation at the leading edge of migrating cells. Plays a role in regulation of apoptosis, possibly through control of CASP3. May be involved in a redox-related process; Belongs to the SelWTH family (115 aa)
     
   
  0.774
GRB7
Growth factor receptor-bound protein 7; Adapter protein that interacts with the cytoplasmic domain of numerous receptor kinases and modulates down-stream signaling. Promotes activation of down-stream protein kinases, including STAT3, AKT1, MAPK1 and/or MAPK3. Promotes activation of HRAS. Plays a role in signal transduction in response to EGF. Plays a role in the regulation of cell proliferation and cell migration. Plays a role in the assembly and stability of RNA stress granules. Binds to the 5’UTR of target mRNA molecules and represses translation of target mRNA species, when not phos [...] (555 aa)

COL4A3BP
Collagen type IV alpha-3-binding protein; Shelters ceramides and diacylglycerol lipids inside its START domain and mediates the intracellular trafficking of ceramides and diacylglycerol lipids in a non-vesicular manner; Pleckstrin homology domain containing (752 aa)
