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

let-2Collagen alpha-2(IV) chain; Collagen type IV is specific for basement membranes (Probable). Together with fbl-1 and downstream of metalloprotease mig- 17, recruits nidogen nid-1 to the gonad basement membrane thereby probably inducing basement membrane remodeling required for the directional migration of distal tip cells. Required to restrict presynaptic growth at the neuromuscular junctions in late larval stage and in adult motor neurons. Vital for embryonic development. (1759 aa)    
Predicted Functional Partners:
emb-9
Collagen alpha-1(IV) chain; Collagen type IV is specific for basement membranes (Probable). Required to restrict presynaptic growth at the neuromuscular junctions (NMJ) in late larval stage and in adult motor neurons. May play a role in axon regeneration in embryos following injury in D-type motor neurons.

pat-3
Integrin beta pat-3; Integrin alpha ina-1/beta pat-3 is a receptor for laminin. Integrin alpha pat-2/beta pat-3 recognizes the sequence R-G-D in its ligands (Probable). Plays a role in cell migration, morphogenesis and probably in cell-cell interactions. During gonad morphogenesis, involved in distal tip cell (DTC)-mediated guidance of gonad elongation, in maintaining their sharp tapering morphology and in their migration. Component of an integrin containing attachment complex, which is required for muscle development and maintenance. Involved in the assembly of dense bodies and M line [...]

unc-52
Basement membrane proteoglycan; Component of an integrin containing attachment complex, which is required for muscle development and maintenance. Probable structural role in myofilament assembly and/or attachment of the myofilament lattice to the cell membrane. May be an extracellular anchor for integrin receptors in body wall muscles and myoepithelial sheath cells. During the formation of neuromuscular junctions at the larval stage, negatively regulates membrane protrusion from body wall muscles, probably downstream of the integrin complex formed by pat-2 and pat-3. Involved in ovulation.

nid-1
NIDogen (Basement membrane protein).

mig-6
Papilin; Involved in pharynx morphogenesis probably by remodeling the basement membrane. [Isoform b]: Plays a role in post embryonic distal cell tip migration. Essential extracellular matrix (ECM) protein required for hypodermal enclosure in the embryo.
   
 
 0.837
epi-1
Laminin-like protein epi-1; During the formation of neuromuscular junctions at the larval stage, negatively regulates membrane protrusion from body wall muscles, probably downstream of the integrin complex formed by pat-2 and pat-3.
   
 
 0.834
fbl-1
Fibulin-1; Incorporated into fibronectin-containing matrix fibers. Plays a role in cell adhesion and migration along protein fibers within the extracellular matrix (ECM). Important for certain developmental processes and contributes to the supramolecular organization of ECM architecture, in particular to those of basement membranes. [Isoform c]: Involved in the assembly of the flexible hemicentin-containing tracks found joining the pharynx and body-wall- muscle basement membranes; Belongs to the fibulin family.
   
 
 0.832
ost-1
SPARC; Has a high affinity for collagen. Affects nematode body morphology and mobility. Essential for C.elegans development and muscle function. The cysteine-rich region could have protease inhibitory activity or may provide the framework for a protein binding module. Probable role in skeletal morphogenesis; Belongs to the SPARC family.
   
 
 0.785
mig-17
Metalloprotease mig-17; Metalloprotease. Acts in the basement membrane to control directional migration of distal tip cells (DTCs) along the body wall basement membranes, a key step that promotes gonad morphogenesis. Regulates DTC migration probably by recruiting fibulin fbl-1, type IV collagen let-2 and nidogen nid-1 to the gonad basement membrane thereby promoting the remodeling of the basement membrane. During larval development and probably upstream of basement membrane proteins fbl-1, let-2 and nid-1, regulates pharynx length, probably by regulating pharyngeal cell length. Does no [...]

mig-18
Abnormal cell migration protein 18; Required for the directional control of distal tip cell migration during gonadogenesis, probably by recruiting fibulin fbl-1 to the gonad basement membrane.
