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

stratGuanine nucleotide exchange factor MSS4 homolog; Guanine-nucleotide-releasing protein that acts on members of the sec4/ypt1/rab subfamily such as Rab8. During egg development, essential for establishing and maintaining epithelial cell polarity by regulating the correct polarized deposition of basal membrane (BM) proteins such as trol/Pcan and vkg/Coll IV to the basal surface of follicular epithelial (FE) cells. Likely to function by restricting the activity of the vesicle transport regulator Rab8 to the basal membrane, and thus directs BM protein-containing vesicles to the basal side o [...] (122 aa)    
Predicted Functional Partners:
Mtl
Mig-2-like (Mtl) encodes a Rho GTPase involved in actin organization regulation. It contributes to multiple actin-mediated processes including dorsal closure, wound healing, cell migration, germ band shortening and salivary gland morphogenesis.
      
 0.923
Cdc42
Cdc42 (Cdc42) encodes a GTPase signaling protein that acts as a molecular switch and functions as key regulator of the actin cytoskeleton. It plays a central role in diverse biological processes including actin cytoskeleton organization, mophogenesis, hemocyte migration, cell polarity, and wound repair.
      
 0.920
Rab1
FI01544p; Rab1 (Rab1) encodes a small GTPase which regulates endoplasmic reticulum to Golgi and intra Golgi trafficking through different effectors. It has been involved in Notch signaling, cell migration, autophagy and cytokinesis.
   
 
 0.915
Arf51F
ADP-ribosylation factor 6; GTP-binding protein involved in protein trafficking; may modulate vesicle budding and uncoating within the Golgi apparatus (By similarity). Promotes cell movement and remodeling of the actin cytoskeleton during compound eye morphogenesis. Required for normal ethanol-induced tolerance and preference. Probably after Efa6-mediated activation, counteracts ethanol-induced sedation.
   
  
 0.905
RtGEF
Rho-type guanine nucleotide exchange factor (RtGEF) encodes a putative Rho-type guanine nucleotide exchange factor for the GTPases encoded by Rac1 and Cdc42. It signals through the sterile-20 kinases encoded by Pak and hpo. The product of RtGEF contributes to regulation of postsynaptic structure, post synaptic muscle development, protein localization and the growth of epithelial tissue.
      
 0.905
ric8a
Synembryn; Guanine nucleotide exchange factor (GEF), which can activate some, but not all, G-alpha proteins independently of G-protein coupled receptors. Acts by exchanging bound GDP for free GTP. Plays a key role in asymmetric spindle positioning, a step for asymmetric cell division that generates cell diversity during development by activating G(i) alpha protein independently of G-protein coupled receptors. In addition to its GEF activity, it plays an essential role in cortical subcellular localization of heterotrimeric G proteins, suggesting it acts as a facilitator of G-alpha funct [...]

CG9175
FI09914p; GTPase activator activity; Sar guanyl-nucleotide exchange factor activity; GTPase binding. It is involved in the biological process described with: cell morphogenesis; regulation of COPII vesicle coating; protein secretion.
      
 0.903
garz
Gartenzwerg, isoform B; Gartenzwerg (garz) encodes a guanine nucleotide exchange factor localized to the cis-Golgi apparatus. The roles of the product of garz include membrane and protein trafficking between the Golgi apparatus and the endoplasmic reticulum. It is required for epithelial morphogenesis in the embryo.
      
 0.896
Rcc1
Regulator of chromosome condensation 1 (Rcc1) encodes the guanine-nucleotide exchange factor for the product of Ran. It promotes the nucleo-cytoplasmic shuttling of specific proteins and regulates chromatin condensation. The roles of Rcc1 product include cell proliferation, cell survival, apoptosis, epigenetic regulation, and neuronal specification.
   
  
 0.883
Rab8
Rab8, isoform A; Rab8 (Rab8) encodes a member of the Rab GTPase family that regulates the function of the recycling endosome, where it localizes.
