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 Size
small nodes:
protein of unknown 3D structure
protein of unknown 3D structure
large nodes:
some 3D structure is known or predicted
some 3D structure is known or predicted
Node Color
colored nodes:
query proteins and first shell of interactors
query proteins and first shell of interactors
white nodes:
second shell of interactors
second shell of interactors
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

Your Input:

 | APOA5 | apolipoprotein A-V; Minor apolipoprotein mainly associated with HDL and to a lesser extent with VLDL. May also be associated with chylomicrons. Important determinant of plasma triglyceride (TG) levels by both being a potent stimulator of apo-CII lipoprotein lipase (LPL) TG hydrolysis and a inhibitor of the hepatic VLDL-TG production rate (without affecting the VLDL-apoB production rate) (By similarity). Activates poorly lecithin-cholesterol acyltransferase (LCAT) and does not enhance efflux of cholesterol from macrophages (366 aa) | ||
 | APOC3 | apolipoprotein C-III; Inhibits lipoprotein lipase and hepatic lipase and decreases the uptake of lymph chylomicrons by hepatic cells. This suggests that it delays the catabolism of triglyceride-rich particles (99 aa) | ||
 | LTF | lactotransferrin (710 aa) | ||
 | RBP2 | retinol binding protein 2, cellular; Intracellular transport of retinol (134 aa) | ||
 | RBP1 | retinol binding protein 1, cellular; Intracellular transport of retinol (197 aa) | ||
 | APOA1 | apolipoprotein A-I; Participates in the reverse transport of cholesterol from tissues to the liver for excretion by promoting cholesterol efflux from tissues and by acting as a cofactor for the lecithin cholesterol acyltransferase (LCAT). As part of the SPAP complex, activates spermatozoa motility (267 aa) | ||
 | TTR | transthyretin; Thyroid hormone-binding protein. Probably transports thyroxine from the bloodstream to the brain (147 aa) | ||
 | IAPP | islet amyloid polypeptide; Selectively inhibits insulin-stimulated glucose utilization and glycogen deposition in muscle, while not affecting adipocyte glucose metabolism (89 aa) | ||
 | APOE | apolipoprotein E; Mediates the binding, internalization, and catabolism of lipoprotein particles. It can serve as a ligand for the LDL (apo B/E) receptor and for the specific apo-E receptor (chylomicron remnant) of hepatic tissues (317 aa) | ||
 | LRP2 | low density lipoprotein receptor-related protein 2; Acts together with cubilin to mediate HDL endocytosis (By similarity). May participate in regulation of parathyroid- hormone and para-thyroid-hormone-related protein release (4655 aa) | ||
 | GPC1 | glypican 1; Cell surface proteoglycan that bears heparan sulfate. Binds, via the heparan sulfate side chains, alpha-4 (V) collagen and participates in Schwann cell myelination (By similarity). May act as a catalyst in increasing the rate of conversion of prion protein PRPN(C) to PRNP(Sc) via associating (via the heparan sulfate side chains) with both forms of PRPN, targeting them to lipid rafts and facilitating their interaction. Required for proper skeletal muscle differentiation by sequestering FGF2 in lipid rafts preventing its binding to receptors (FGFRs) and inhibiting the FGF-med [...] (558 aa) | ||
 | MFGE8 | milk fat globule-EGF factor 8 protein; Plays an important role in the maintenance of intestinal epithelial homeostasis and the promotion of mucosal healing. Promotes VEGF-dependent neovascularization (By similarity). Contributes to phagocytic removal of apoptotic cells in many tissues. Specific ligand for the alpha-v/beta-3 and alpha-v/beta-5 receptors. Also binds to phosphatidylserine-enriched cell surfaces in a receptor-independent manner. Zona pellucida-binding protein which may play a role in gamete interaction. Binds specifically to rotavirus and inhibits its replication (387 aa) | ||
 | GPC2 | glypican 2; Cell surface proteoglycan that bears heparan sulfate. May fulfill a function related to the motile behaviors of developing neurons (By similarity) (579 aa) | ||
 | FGA | fibrinogen alpha chain; Fibrinogen has a double function- yielding monomers that polymerize into fibrin and acting as a cofactor in platelet aggregation (866 aa) | ||
 | SDC2 | syndecan 2; Cell surface proteoglycan that bears heparan sulfate. Regulates dendritic arbor morphogenesis (By similarity) (201 aa) | ||
 | LPL | lipoprotein lipase; The primary function of this lipase is the hydrolysis of triglycerides of circulating chylomicrons and very low density lipoproteins (VLDL). Binding to heparin sulfate proteogylcans at the cell surface is vital to the function. The apolipoprotein, APOC2, acts as a coactivator of LPL activity in the presence of lipids on the luminal surface of vascular endothelium (By similarity) (475 aa) | ||
 | P4HB | prolyl 4-hydroxylase, beta polypeptide; This multifunctional protein catalyzes the formation, breakage and rearrangement of disulfide bonds. At the cell surface, seems to act as a reductase that cleaves disulfide bonds of proteins attached to the cell. May therefore cause structural modifications of exofacial proteins. Inside the cell, seems to form/rearrange disulfide bonds of nascent proteins. At high concentrations, functions as a chaperone that inhibits aggregation of misfolded proteins. At low concentrations, facilitates aggregation (anti-chaperone activity). May be involved with [...] (508 aa) | ||
 | CALCA | calcitonin-related polypeptide alpha; Calcitonin causes a rapid but short-lived drop in the level of calcium and phosphate in blood by promoting the incorporation of those ions in the bones (141 aa) | ||
 | LRAT | lecithin retinol acyltransferase (phosphatidylcholine--retinol O-acyltransferase); Transfers the acyl group from the sn-1 position of phosphatidylcholine to all-trans retinol, producing all-trans retinyl esters. Retinyl esters are storage forms of vitamin A. LRAT plays a critical role in vision. It provides the all-trans retinyl ester substrates for the isomerohydrolase which processes the esters into 11-cis-retinol in the retinal pigment epithelium; due to a membrane-associated alcohol dehydrogenase, 11 cis-retinol is oxidized and converted into 11-cis-retinaldehyde which is the chrom [...] (230 aa) | ||
 | SNCA | synuclein, alpha (non A4 component of amyloid precursor); May be involved in the regulation of dopamine release and transport. Induces fibrillization of microtubule-associated protein tau. Reduces neuronal responsiveness to various apoptotic stimuli, leading to a decreased caspase-3 activation (140 aa) | ||
 | SDC3 | syndecan 3; Cell surface proteoglycan that may bear heparan sulfate (By similarity). May have a role in the organization of cell shape by affecting the actin cytoskeleton, possibly by transferring signals from the cell surface in a sugar-dependent mechanism (442 aa) | ||
 | SAA1 | serum amyloid A1; Major acute phase reactant. Apolipoprotein of the HDL complex (By similarity) (122 aa) | ||
 | APOA4 | apolipoprotein A-IV; May have a role in chylomicrons and VLDL secretion and catabolism. Required for efficient activation of lipoprotein lipase by ApoC-II; potent activator of LCAT. Apoa-IV is a major component of HDL and chylomicrons (396 aa) | ||
 | APOA2 | apolipoprotein A-II; May stabilize HDL (high density lipoprotein) structure by its association with lipids, and affect the HDL metabolism (100 aa) | ||
