>cd04119 RJL RJL (RabJ-Like) subfamily. RJLs are found in many protists and as chimeras with C-terminal DNAJ domains in deuterostome metazoa. They are not found in plants, fungi, and protostome metazoa, suggesting a horizontal gene transfer between protists and deuterostome metazoa. RJLs lack any known membrane targeting signal and contain a degenerate phosphate/magnesium-binding 3 (PM3) motif, suggesting an impaired ability to hydrolyze GTP. GTPase activating proteins (GAPs) interact with GTP-bound Rab and accelerate the hydrolysis of GTP to GDP. Guanine nucleotide exchange factors (GEFs) interact with GDP-bound Rabs to promote the formation of the GTP-bound state. Rabs are further regulated by guanine nucleotide dissociation inhibitors (GDIs), which facilitate Rab recycling by masking C-terminal lipid binding and promoting cytosolic localization.
