Web28 mag 2010 · Arfs are small G proteins that have a key role in vesicle trafficking and cytoskeletal remodeling. ArfGAP proteins stimulate Arf intrinsic GTP hydrolysis by a mechanism that is still unresolved. Using a fusion construct we solved the structure of the ArfGAP ASAP3 in complex with Arf6 in the transition state. This structure clarifies the … Web1 lug 1998 · In GAP-334, Arg789 (Arg1276 in neurofibromin) is extremely important for GTPase acceleration; even conservative mutation of this residue, to lysine, has dramatic effects. Arg903 (Arg1301) is less critical, but double mutants such as Arg789→Lys Arg903→Ala are unable to accelerate the GTPase activity beyond the intrinsic rate of …
Web10 mag 2024 · Donahue et al. (2003) identified a naturally occurring arg1147-to-cys mutation in exon 48 of the Col2a1 gene in mice. The mutation was considered analogous to the arg789-to-cys mutation in the COL2A1 gene (R789C; 120140.0016), which had been described in 2 unrelated patients with SEDC (Chan et al. (1993, 1995)).
