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 describes the C-terminal domain in Rab-3A-interacting protein (Rabin 8) and other guanine nucleotide exchange factors (GEFs) found in eukaryotes. Rabin 8 is part of the SEC2 family that functions as a GEF that activate GTPases, primarily RAB3A, RAB8A and RAB8B. The C-terminal of Rabin 8 has five alpha-helices and three strands of antiparallel beta-sheet. It was recently shown to interact with Rab11 at an unusual effector-binding site neighbouring the canonical FIP3-binding site [1].
