26814130 DiRas1 expression inhibits malignant features of cancers in part by nonproductively binding to SmgGDS and inhibiting the binding of other small GTPases to SmgGDS
26598509 results indicate that statins selectively up-regulate SmgGDS in endothelial cells, for which the beta1-integrin/Akt1 pathway may be involved, demonstrating the novel aspects of the pleiotropic effects of statins
24552806 SmgGDS promotes cell cycle progression in multiple types of cancer, making SmgGDS a valuable target for cancer therapeutics.
24415755 this study provides evidence that SmgGDS-607 associates with GTPases through recognition of the last amino acid in the CAAX motif.
24349085 TG2 contributes to apoptosis induction in Jurkat T cells by modulating Ca2+ homeostasis via cross-linking RAP1GDS1.
24197117 findings identify SmgGDS-558 as an activator of RhoA and NF-kB in breast cancer, and demonstrate a functional role for SmgGDS-558 in the proliferation of breast cancer cells and tumorigenesis.
23898208 HIV-1 Tat downregulates the expression of RAP1, GTP-GDP dissociation stimulator 1 (RAP1GDS1; GDS1) in human primary T cells
23640485 These results indicate that statins exert their pleiotropic effects through SmgGDS upregulation with a resultant Rac1 degradation and reduced oxidative stress in animals and humans.
21429211 findings provide compelling evidence of a novel role for junctional adhesion molecule-A (JAM-A)in driving breast cancer cell migration via activation of Rap1 GTPase and beta1-integrin
21242305 Results indicate that SmgGDS is a bona fide GEF that specifically activates RhoA and RhoC through a unique mechanism not used by other Rho family exchange factors.
20709748 Results indicate that guanine nucleotide exchange and interactions with SmgGDS splice variants can regulate the entrance and passage of PBR-possessing small GTPases through the prenylation pathway.
20209136 C3G stimulates guanine nucleotide exchange on Drosophila Rap GTPases in vitro
20190816 ALK activation of Rap1 via the Rap1-specific GEF C3Gmay contribute to cell proliferation and oncogenesis of neuroblastoma.
19546222 Epac activates the small G proteins Rap1 and Rab3A to achieve exocytosis.
19260141 Observational study and genome-wide association study of gene-disease association. (HuGE Navigator)
17951244 SmgGDS promotes the malignant Non-small cell lung carcinoma (NSCLC)phenotype and is an intriguing therapeutic target in NSCLC.
14615375 results demonstrate that B-CLL cells uniquely activate Rap1 in response to PDE4 inhibitors and suggest that physiologic stimuli that activate EPAC may transmit an antiapoptotic signal
12690117 activated by turbulence and is involved in integrin [alpha]IIb[beta]3-mediated cell adhesion in human megakaryocytes
