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

Gprk2G protein-coupled receptor kinase 2 (Gprk2) encodes a member of a family of serine/threonine kinases that modulate G-protein coupled receptors. It is required for female fertility, normal egg shape, and normal egg cAMP levels. It is also implicated in Hedgehog signaling and olfactory rhythmicity; Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. GPRK subfamily. (714 aa)    
Predicted Functional Partners:
smo
Protein smoothened; Segment polarity protein required for correct patterning of every segment. G protein-coupled receptor that associates with the patched protein (ptc) to transduce the hedgehog (hh) signal through the activation of an inhibitory G-protein. In the absence of hh, ptc represses the constitutive signaling activity of smo through fused (fu). Essential component of a hh-signaling pathway which regulates the Duox-dependent gut immune response to bacterial uracil; required to activate Cad99C-dependent endosome formation, norpA-dependent Ca2+ mobilization and p38 MAPK, which a [...]

Gbeta5
RH17413p; GTPase activator activity; G-protein gamma-subunit binding. It is involved in the biological process described with: G protein-coupled receptor signaling pathway; dopamine receptor signaling pathway; positive regulation of GTPase activity.
   
 
 0.913
Gprk1
G protein-coupled receptor kinase 1; Specifically phosphorylates the activated forms of G protein- coupled receptors; Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. GPRK subfamily.
     
0.912
krz
Kurtz, isoform A; Kurtz (krz) encodes a beta-arrestin (non-visual arrestin) involved in the desensitization and endocytic internalization of G protein coupled receptors, thus downregulating their activity. It also controls other signaling pathways, including Notch, receptor tyrosine kinase, Hedgehog, and Toll. It is required maternally for normal embryonic patterning and zygotically for larval viability.

Arr2
Phosrestin-1; Arrestin 2 (Arr2) encodes a protein involved in rhodopsin inactivation that contributes to photoreceptor maintenance and smell and sound perception.
   
 0.789
Gbeta13F
Guanine nucleotide-binding protein subunit beta-1; G protein beta-subunit 13F (Gbeta13F) encodes an ubiquitous, maternal product required for gastrulation movements of early embryo and regulating medial (mesoderm and ectoderm) and junctional Myosin II (ectoderm) via RhoI pathway. The product of Gbeta13F is detected apically and at adherens junctions.
   
 
 0.789
Gbeta76C
Guanine nucleotide-binding protein subunit beta-2; G protein beta-subunit 76C (Gbeta76C) encodes a protein that forms a Gbeta-gamma complex that is anchored to the plasma membrane via lipid modification of the gamma-subunit. The Gbeta-gamma complex plays an essential role in phototransduction by presenting the Gqalpha-subunit to rhodopsin GPCRs for efficient activation, and preventing spontaneous GDP-GTP exchange on the Gqalpha-subunit.
   
 
 0.760
Git
G protein-coupled receptor kinase interacting ArfGAP (Git) encodes an Arf-GAP that forms a scaffold with the Rho-type guanine nucleotide exchange factor encoded by pix aiding in activation of the kinase encoded by Pak. The product of RtGEF has roles in muscle morphogenesis, synaptic vesicle recycling, and regulation of tissue growth.

hh
Protein hedgehog C-product; Intercellular signal essential for a variety of patterning events during development. Establishes the anterior-posterior axis of the embryonic segments and patterns the larval imaginal disks. Binds to the patched (ptc) receptor, which functions in association with smoothened (smo), to activate the transcription of target genes wingless (wg), decapentaplegic (dpp) and ptc. In the absence of hh, ptc represses the constitutive signaling activity of smo through fused (fu). Essential component of a signaling pathway which regulates the Duox-dependent gut immune r [...]
    
 
 0.737
ptc
Protein patched; Segmentation polarity protein. Acts as a receptor for the hedgehog protein (HH). Associates with the smoothened protein (SMO) to transduce the hedgehog signal leading to the activation of wingless, decapentaplegic and patched itself. Participates in cell interactions that establish pattern within the segment and the imaginal disks during development. In the absence of HH, represses the constitutive signaling activity of smo through fused (FU).
