Supplementary information

RAB39B also known as Ras-related protein Rab-39B is a member of the Rab family of small GTPases which has a molecular mass of approximately 26 kDa. RAB39B is expressed in several tissues but it shows higher expression levels in the brain. Mechanically RAB39B is involved in the regulation of intracellular vesicle trafficking specifically linked to endosome dynamics. This protein functions by switching between active GTP-bound and inactive GDP-bound states influencing membrane trafficking along actin and tubulin networks.
Biological function summary

RAB39B plays a role in synapse function and maintenance. This protein associates with cellular membranes and is involved in the trafficking of AMPA receptors to the neuronal surface which impacts synaptic plasticity and neurotransmission. Although not typically described as part of a large complex RAB39B works in close association with other synaptic proteins to ensure proper synaptic function. Its function in neurons highlights the importance of precise vesicular trafficking in neurotransmitter release and synaptic strength.

Pathways

RAB39B is integral to the endocytic trafficking and recycling pathways. It collaborates with key proteins like Rab7 and Rab5 in these cellular processes ensuring the proper sorting and recycling of synaptic vesicles. This precise control contributes to cellular homeostasis and efficient signal transmission at synapses which is critical for neuronal communication and overall brain function.

RAB39B is linked to neurodevelopmental disorders and has a significant connection to Parkinson's disease. Mutations in RAB39B can lead to intellectual disabilities and autism spectrum disorders. In the context of Parkinson's disease altered RAB39B function has been associated with the pathogenesis where it interacts with alpha-synuclein a protein significantly implicated in the disorder. These connections highlight the importance of RAB39B in maintaining neurological health and its potential as a therapeutic target.

Target data

The small GTPases Rab are key regulators of intracellular membrane trafficking, from the formation of transport vesicles to their fusion with membranes. Rabs cycle between an inactive GDP-bound form and an active GTP-bound form that is able to recruit to membranes different sets of downstream effectors directly responsible for vesicle formation, movement, tethering and fusion (PubMed : 27103069). RAB39B is involved in autophagy and may function in autophagosome formation (PubMed : 27103069, PubMed : 37821429). Binds downstream effector PICK1 to ensure selectively GRIA2 exit from the endoplasmic reticulum to the Golgi and to regulate AMPAR composition at the post-synapses and thus synaptic transmission (By similarity). May regulate the homeostasis of SNCA/alpha-synuclein (By similarity).
