>cd04107 Rab32_Rab38 Rab38/Rab32 subfamily. Rab32 and Rab38 are members of the Rab family of small GTPases. Human Rab32 was first identified in platelets but it is expressed in a variety of cell types, where it functions as an A-kinase anchoring protein (AKAP). Rab38 has been shown to be melanocyte-specific. 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.
