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

vkgViking, isoform A; Viking (vkg) encodes a subunit of Collagen IV and a major component of basement membranes. It is secreted by haemocytes and fat body cells and is required for the normal morphogenesis of many tissues. It also contributes to TGF-beta signalling in the early embryo and the developing Malpighian tubules. (1940 aa)    
Predicted Functional Partners:
Col4a1
Collagen alpha-1(IV) chain; Collagen type IV alpha 1 (Col4a1) encodes a subunit of Collagen IV and a major component of basement membranes. It is required for muscle and epithelium integrity.
  
0.999
Ndg
Nidogen; Cell adhesion glycoprotein which is widely distributed in basement membranes. Involved in cell-extracellular matrix (ECM) interactions probably by connecting the laminin and collagen IV networks. Required for permeability and mechanical stability of basement membranes, and ECM dependent neural plasticity. Not involved in assembly of the embryonic basement membrane.

prc
Pericardin (prc) encodes a type IV collagen-like extracellular matrix protein involved in heart development.

mys
Integrin beta-PS; Integrin alpha-PS1/beta-PS is a receptor for laminin. Integrin alpha-PS2/beta-PS is a receptor for Tig, wb and Ten-m. Contributes to endodermal integrity and adhesion between the midgut epithelium and the surrounding visceral muscle. Essential for migration of the primordial midgut cells and for maintaining, but not establishing, cell polarity in the midgut epithelium. The two beta subunits mediate midgut migration by distinct mechanisms: beta-PS requires rhea/talin and Itgbn does not. Required for rhea/talin correct cellular localization in the midgut. Required for m [...]

Itgbn
Integrin beta-nu; Contributes to endodermal integrity and adhesion between the midgut epithelium and the surrounding visceral muscle. Essential for migration of the primordial midgut cells and for maintaining, but not establishing, cell polarity in the midgut epithelium. Can only partially compensate for the loss of beta-PS integrin during primordial midgut cell migration. The two beta subunits mediate midgut migration by distinct mechanisms: beta-PS requires rhea/Talin and beta-nu does not. Integrin alpha-PS3/beta-nu is required for effective phagocytosis of apoptotic cells during emb [...]

LanA
Laminin subunit alpha; Binding to cells via a high affinity receptor, laminin is thought to mediate the attachment, migration and organization of cells into tissues during embryonic development by interacting with other extracellular matrix components. Activates presynaptic signaling involving integrin alpha-PS3/beta-nu and Fak to suppress neuromuscular junction (NMJ) growth during larval development and during low crawling activity, but not during higher-crawling conditions. Mediates, together with integrin alpha-PS3/beta-nu, glutamate receptor-modulated NMJ growth.

SPARC
Secreted protein, acidic, cysteine-rich (SPARC) encodes a small calcium and growth factor-binding secreted glycoprotein that is enriched in basement membranes. During cell competition, it is expressed in "loser" cells so they can avoid apoptosis mediated by the products of fwe and azot.
   
 
 0.943
LanB2
Laminin B2 (LanB2) encodes a subunit of laminin, a heterotrimeric protein found in the extracellular matrix (ECM) and a major component of the basal lamina. Laminins interact with a variety of cell surface molecules such as integrin receptors and other secreted ECM components. It contributes to ECM organization, tissue adhesion, cell motility and developmental patterning.

dpp
Protein decapentaplegic; Required during oogenesis for eggshell patterning and dorsal/ventral patterning of the embryo. Acts as a morphogen during embryogenesis to pattern the dorsal/ventral axis, specifying dorsal ectoderm and amnioserosa cell fate within the dorsal half of the embryo; this activity is antagonized by binding to sog and tsg. Induces the formation of visceral mesoderm and the heart in early embryos. Required later in embryogenesis for dorsal closure and patterning of the hindgut. Also functions postembryonically as a long-range morphogen during imaginal disk development [...]

Peroxidasin; Plays a role in extracellular matrix consolidation, phagocytosis and defense.
