Includes sub-families Ras, Rab, Rac, Ral, Ran, Rap Ypt1 and more. Shares P-loop motif with GTP_EFTU, arf and myosin_head. See Pfam:PF00009 Pfam:PF00025, Pfam:PF00063. As regards Rab GTPases, these are important regulators of vesicle formation, motil ...
Includes sub-families Ras, Rab, Rac, Ral, Ran, Rap Ypt1 and more. Shares P-loop motif with GTP_EFTU, arf and myosin_head. See Pfam:PF00009 Pfam:PF00025, Pfam:PF00063. As regards Rab GTPases, these are important regulators of vesicle formation, motility and fusion. They share a fold in common with all Ras GTPases: this is a six-stranded beta-sheet surrounded by five alpha-helices [1].
This entry represents the m3G cap-binding domain of Snurportin1 (SPN1), a nuclear import adaptor for m3G-capped spliceosomal U small nucleoproteins (snRNPs). After capping and assembly, the U snRNPs are transported into the nucleus by SPN1 and import ...
This entry represents the m3G cap-binding domain of Snurportin1 (SPN1), a nuclear import adaptor for m3G-capped spliceosomal U small nucleoproteins (snRNPs). After capping and assembly, the U snRNPs are transported into the nucleus by SPN1 and importin beta; SPN1 is then returned to the cytoplasm by exportin 1 (CRM1) [1-5].

CRM1 is the major nuclear export receptor. During translocation through the nuclear pore, transport complexes transiently interact with phenylalanine-glycine (FG) repeats of multiple nucleoporins. On the cytoplasmic side of the nuclear pore, CRM1 tightly interacts with the nucleoporin Nup214. Nup214 binds to N- and C-terminal regions of CRM1, thereby clamping CRM1 in a closed conformation and stabilizing the export complex. This entry represents an FG repeat region within the C terminus of Nup214 which is required for its interaction with CRM1 [1].
