    1. Silencing of SmgGDS, a Novel mTORC1 Inducer That Binds to RHEBs, Inhibits Malignant Mesothelioma Cell Proliferation.
      Title: Silencing of SmgGDS, a Novel mTORC1 Inducer That Binds to RHEBs, Inhibits Malignant Mesothelioma Cell Proliferation.
    2. Mutated RAP1GDS1 causes a new syndrome of dysmorphic feature, intellectual disability & speech delay.
      Title: Mutated RAP1GDS1 causes a new syndrome of dysmorphic feature, intellectual disability & speech delay.
    3. Targeting SmgGDS splicing to lower the protein isoform ratio is effective to inhibit the malignant phenotype generated by small GTPases.
      Title: Splice switching an oncogenic ratio of SmgGDS isoforms as a strategy to diminish malignancy.
    4. The competitive binding affinities of the small GTPase for SmgGDS-607 and FTase dictate the extent of this inhibition. SmgGDS-607 increases the rate of farnesylation of HRas by enhancing product release from FTase.
      Title: The chaperone SmgGDS-607 has a dual role, both activating and inhibiting farnesylation of small GTPases.
    5. SmgGDS-607 completely inhibits RhoA prenylation catalyzed by protein geranylgeranyltransferase I (GGTase-I) in an in vitro radiolabel incorporation assay. SmgGDS-607 inhibits prenylation by binding to and blocking access to the C-terminal tail of the small GTPase (substrate sequestration mechanism) rather than via inhibition of the prenyltransferase activity.
      Title: SmgGDS-607 Regulation of RhoA GTPase Prenylation Is Nucleotide-Dependent.
    6. Study reveals a cryptic pocket by which SmgGDS-558 accommodates RhoA prenylation, loosening the structure of Rho when it interacts with SmgGDS, which may enable drug development strategies for targeting SmgGDS and small GTPases.
      Title: GEF mechanism revealed by the structure of SmgGDS-558 and farnesylated RhoA complex and its implication for a chaperone mechanism.
    7. a novel nuclear role for SmgGDS in protecting malignant cells from nucleolar stress, thus promoting cell cycle progression and tumorigenesis.
      Title: SmgGDS is a transient nucleolar protein that protects cells from nucleolar stress and promotes the cell cycle by regulating DREAM complex gene expression.
    8. Data suggest that SmgGDS-558 splice variant exhibits a fold containing tandem copies of armadillo-repeat motifs not present in other guanine nucleotide exchange factors (GEFs); SmgGDS harbors distinct positively and negatively charged regions, both of which play critical roles in binding to RhoA and in GEF activity. (SmgGDS = smg p21 stimulatory GDP exchange protein; RhoA = ras homolog gene family, member A)
      Title: Structure-based analysis of the guanine nucleotide exchange factor SmgGDS reveals armadillo-repeat motifs and key regions for activity and GTPase binding.
    9. Unlike Rap1B, phosphorylation in the polybasic region of Rap1A does not detectably inhibit its prenylation or its binding to SmgGDS-607.
      Title: Differences in the Phosphorylation-Dependent Regulation of Prenylation of Rap1A and Rap1B.
    10. In addition, a PINK1 mutant, which induced mitochondrial enlargement and had been considered as a Drosophila model of Parkinson's disease (PD), caused fly muscle defects, and the loss of vimar could rescue these defects. Furthermore, we found that the mammalian homolog of Vimar, RAP1GDS1, played a similar role in regulating mitochondrial morphology, suggesting a functional conservation of this GEF member.
      Title: Vimar Is a Novel Regulator of Mitochondrial Fission through Miro.

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
