>cd04125 RabA_like RabA-like subfamily. RabA was first identified in D. discoideum, where its expression levels were compared to other Rabs in growing and developing cells. The RabA mRNA levels were below the level of detection by Northern blot analysis, suggesting a very low level of expression. The function of RabA remains unknown. 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. Most Rab GTPases contain a lipid modification site at the C-terminus, with sequence motifs CC, CXC, or CCX. Lipid binding is essential for membrane attachment, a key feature of most Rab proteins.
