RAB39. a member of the Rab GTPase family, plays a critical role in regulating intracellular membrane trafficking, vesicle transport, and autophagy. This small GTPase cycles between GTP-bound (active) and GDP-bound (inactive) states, interacting with effector proteins to direct organelle-specific cargo sorting and membrane fusion. Human RAB39 exists as two isoforms: RAB39A and RAB39B, encoded by distinct genes. RAB39B, located on the X chromosome, has drawn particular attention due to its association with neurodevelopmental disorders. Loss-of-function mutations in RAB39B are linked to X-linked intellectual disability, autism spectrum disorders, and early-onset Parkinson’s disease, implicating its role in neuronal maintenance and synaptic vesicle dynamics. Studies suggest RAB39B influences α-synuclein homeostasis, with dysregulation potentially contributing to pathological protein aggregation. Structurally, RAB39B contains conserved GTPase domains and hypervariable C-terminal regions for membrane anchoring. While RAB39A's functions are less understood, it is implicated in inflammatory responses and glioblastoma progression. Current research focuses on deciphering RAB39 isoforms' distinct vesicular trafficking pathways, their interplay with neurodegenerative mechanisms, and therapeutic targeting. However, functional redundancies with other Rab proteins and tissue-specific expression patterns complicate mechanistic studies. Further characterization of RAB39’s interactome and signaling networks remains essential for understanding its pathophysiological roles.
