13. Mechanistic insights into specificity, activity, and regulatory elements of the regulator of G-protein signaling (RGS)-containing Rho-specific guanine nucleotide exchange factors (GEFs) p115, PDZ-RhoGEF (PRG), and leukemia-associated RhoGEF (LARG). PMID: 21454492
14. a novel physical and functional interaction between ABCA1 and PDZ-RhoGEF/LARG, which activates RhoA, resulting in ABCA1 stabilization and cholesterol efflux activity. PMID: 20348106
15. Regulation of G protein-linked guanine nucleotide exchange factors for Rho, PDZ-RhoGEF, and LARG by tyrosine phosphorylation: evidence of a role for focal adhesion kinase PMID: 11799111
16. Plexin B regulates Rho through the guanine nucleotide exchange factors leukemia-associated protein and PDZ-RhoGEF. PMID: 12183458
17. LARG plays a critical role in plexin-B1 signaling to stimulate Rho activation and cytoskeletal reorganization. PMID: 12196628
18. Rho activation through Galpha12 and the regulation of RhoGEFs by heterotrimeric G proteins G1213 is further modulated by tyrosine phosphorylated leukemia-associated RhoGEF. PMID: 12515866
19. Data show that different rho guanine nucleotide exchange factors (rhoGEFs; p115rhoGEF, LARG and PDZrhoGEF) mediate downstream rho signaling by the thrombin and lysophosphatidic acid receptors. PMID: 15143072
20. analysis of LARG RhoA binding and nucleotide exchange structure PMID: 15331592
21. CD44 interaction with LARG and EGFR plays a pivotal role in Rho/Ras co-activation, PLC epsilon-Ca2+ signaling, and Raf/ERK up-regulation required for CaMKII-mediated cytoskeleton function and in head and neck squamous cell carcinoma progression PMID: 16565089
