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

porProtein-serine O-palmitoleoyltransferase porcupine; Protein-serine O-palmitoleoyltransferase that acts as a key regulator of the Wnt signaling pathway by mediating the attachment of palmitoleate, a 16-carbon monounsaturated fatty acid (C16:1), to Wnt proteins. Serine palmitoleylation of Wnt proteins is required for efficient binding to frizzled receptors (By similarity). Also facilitates the glycosylation of Wnt family members, including wg and Wnt5. The cotranslational disulfide bond formation of wg competes with the N-glycosylation. Porc stimulates the post-translational N- glycosyla [...] (525 aa)    
Predicted Functional Partners:
wg
Protein wingless; Binds as a ligand to a family of frizzled seven-transmembrane receptors and acts through a cascade of genes on the nucleus. Segment polarity protein. May be a growth factor. Acts on neighboring cells to regulate at least one gene, the homeobox segmentation gene engrailed. Wg signal represses arm phosphorylation. Wg signaling operates by inactivating the sgg repression of engrailed autoactivation. Wg and Wnt2 have a role in the developing trachea and together are responsible for all dorsal trunk formation. Wg also acts in the developing epidermis. Acts as a morphogen, [...]

Wnt5
Protein Wnt-5; Binds as a ligand to a family of frizzled seven-transmembrane receptors and acts through a cascade of genes on the nucleus. Probable developmental protein. May be a signaling molecule which affects the development of discrete regions of tissues. Is likely to signal over only few cell diameters. May have a role in limb and CNS development; may be a downstream target of Dll that acts in the specification of these primordia; Belongs to the Wnt family.
   
 0.965
wntD
Wnt inhibitor of Dorsal protein; Binds as a ligand to a family of frizzled seven-transmembrane receptors and acts through a cascade of genes on the nucleus. Belongs to the Wnt family.
    
 0.959
Wnt10
Wnt oncogene analog 10 (Wnt10) encodes a member of the Wnt protein family with unknown function; Belongs to the Wnt family.
    
 0.959
Wnt6
Wnt oncogene analog 6 (Wnt6) encodes a member of the Wnt family that can activate canonical Wnt signaling. It is expressed in the dorsal/ventral boundary of the wing and the maxillary palp. It contributes to maxillary palp formation.
    
 0.954
wls
Protein wntless; A segment polarity gene required for wingless (wg)-dependent patterning processes, acting in both wg-sending cells and wg-target cells. In non-neuronal cells wls directs wg secretion. The wls traffic loop encompasses the Golgi, the cell surface, an endocytic compartment and a retrograde route leading back to the Golgi, and involves clathrin-mediated endocytosis and the retromer complex (a conserved protein complex consisting of Vps35 and Vps26). In neuronal cells (the larval motorneuron NMJ), the wg signal moves across the synapse via the release of wls-containing exos [...]
   
 
 0.771
sgg
Protein kinase shaggy; Required for several developmental events such as syncytial blastoderm formation and embryonic segmentation. Is involved in transcriptional regulation. Required for arm phosphorylation. Wg signaling operates by inactivating the sgg repression of en autoactivation. Negatively controls the neuromuscular junction (NMJ) growth in presynaptic motoneurons. Plays a role in the regulation of microtubule dynamics and actin cytoskeleton during embryogenesis. Required for phosphorylation of sra in activated eggs. Essential for completion of meiosis, possibly by triggering c [...]
      
 0.600
Wnt2
Protein Wnt-2; Binds as a ligand to a family of frizzled seven-transmembrane receptors and acts through a cascade of genes on the nucleus. Segment polarity protein. May function in gonadogenesis and limb development. Wg and Wnt2 have a role in the developing trachea and together are responsible for all dorsal trunk formation.
    
 
 0.559
Wnt4
Protein Wnt-4; Binds as a ligand to a family of frizzled seven-transmembrane receptors and acts through a cascade of genes on the nucleus. Acts downstream of homeotic complex genes in the visceral mesoderm and is required for embryonic segmentation. Also required for cell movement and FAK regulation during ovarian morphogenesis.
    
 
 0.554
dsh
Segment polarity protein dishevelled; Required to establish coherent arrays of polarized cells and segments in embryos. Plays a role in wingless (wg) signaling, possibly through the reception of the wg signal by target cells and subsequent redistribution of arm protein in response to that signal in embryos. This signal seems to be required to establish planar cell polarity and identity.
