Gene Group (FlyBase)
RHO GTPASES -
Rho (Ras Homologous) GTPases are members of the Ras superfamily of small GTPases. They are best characterized for their roles in regulating actin organization. (Adapted from PMID:15731001).
Pathway (FlyBase)
PVR SIGNALING PATHWAY CORE COMPONENTS -
PDGF/VEGF (Platelet-Derived Growth Factor/Vascular Endothelial Growth Factor)-receptor related (Pvr) encodes a receptor tyrosine kinase activated by the binding of PDGF- and VEGF-related factors (Pvf1,Pvf2 or Pvf3). Pvr has been shown to activate the canonical Ras/Raf/MAP kinase (ERK) cascade, the PI3K kinase pathway, TORC1 (FBrf0222697), Rho family small GTPases (FBrf0221764, FBrf0180198) and the JNK cascade (FBrf0180198), in a context-dependent manner. (Adapted from FBrf0222697 and FBrf0221727).
Protein Function (UniProtKB)
Regulates mbt kinase activity and is also required to recruit mbt to adherens junctions (PubMed:12490550). Together with mbt and Frl, regulates photoreceptor cell morphogenesis (PubMed:12490550, PubMed:26801180). Together with Frl, has a role in the neuronal development of mushroom bodies (PubMed:26801180).

Model Confidence:
  • Very high (pLDDT > 90)
  • Confident (90 > pLDDT > 70)
  • Low (70 > pLDDT > 50)
  • Very low (pLDDT < 50)

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

Subunit Structure (UniProtKB)

Interacts with Frl (via GBD/FH3 domain); the interaction is stronger with the GTP bound form of Cdc42 (PubMed:26801180). The GTP-bound but not the GDP-bound form interacts with mbt and gek (PubMed:12490550, PubMed:9371783). When GTP-bound, interacts with Pak (PubMed:8628256).

Additional Descriptive Data

Cdc42 is expressed in all developmental stages. It is expressed ubiquitously in embryos.

Cdc42 transcripts are detected throughout development. In embryos, strong ubiquitous expression is observed in blastoderm stages. The transcript is concentrated at the basal part of the cellular blastoderm. After gastrulation, transcripts become highly enriched in the somatic mesoderm. Transcripts start to appear in the CNS and gut in stage 13. Later, somatic mesoderm expression vanishes but gut and CNS expression persists.

        S2 cells treated with dsRNA generated against this gene show reduced phagocytosis of Candida albicans compared to untreated cells.

        Identified in an RNAi screen for host factors that alter infection of SL2 cells by L.monocytogenes.

        Identified in an RNAi screen for host factors that alter infection of SL2 cells by M.fortuitum.

        dsRNA made from templates generated with primers directed against this gene tested in RNAi screen for effects on Kc167 and S2R+ cell morphology.

        RNAi generated by PCR using primers directed to this gene causes a cell shape change from round to polarized when assayed in Kc167 cells, with the formation of F-actin puncta and microtubule extensions. For both Kc167 and S2R+ cells, reduced F-actin and altered cell shape occur.

        dsRNA made from templates generated with primers directed against this gene is tested in an RNAi screen for effects on actin-based lamella formation.

        Cdc42 appears to be required for the regulation of actin polymerisation and/or myosin activity that is critical for the response of growth cones to midline repulsive signals.

        Cdc42 is necessary for cellular extenion formation, but not for actin cable formation during wound healing in the embryo.

        Cdc42 may be a negative regulator of N signalling.

        Cdc42 has a role in actin filament assembly and plays a role on intercellular interactions between the germ-line and the somatic follicle cells.

        Cdc42, but not Rac1, is an activator of puc expression in a hep dependent manner in imaginal discs.

        Cdc42 has a function in dendritic development.

        ISNb growth cones require Cdc42 for extension to appropriate targets.

        Cdc42 is not allelic to btdl.

        Rac1 and Cdc42 are components of the bsk pathway and are upstream activators of hep and dpp.

        Cdc42, RhoL and Rac1 protein activities are required for normal transfer of cytoplasm from nurse cells to the oocyte.

        Comparison of expression of constitutively active or dominantly negative Cdc42 and Rac1 mutants demonstrates that similar GTPases in the same subfamily have unique roles in morphogenesis in vivo.

        The Rac2 gene may have been derived from the Cdc42 gene by retroposition.
