Rab27abound

Rab27abound is a protein that belongs to the Rab family, which are small GTPases involved in various cellular processes such as vesicular transport, endocytosis, and exocytosis. Rab27abound is specifically expressed in the brain and is involved in the regulation of synaptic vesicle recycling and neurotransmitter release. It plays a crucial role in the maintenance of synaptic function and plasticity, which are essential for learning and memory.

Rab27abound is localized to synaptic vesicles and is recruited to the active zone, where it interacts with other proteins involved in neurotransmitter release, such as syntaxin and SNAP-25. This interaction is thought to facilitate the docking and fusion of synaptic vesicles with the presynaptic membrane, leading to the release of neurotransmitters.

Mutations in the Rab27abound gene have been linked to several neurological disorders, including autism spectrum disorder and intellectual disability. These mutations can disrupt the normal function of Rab27abound and lead to impaired synaptic transmission and plasticity, contributing to the symptoms of these disorders.

In summary, Rab27abound is a Rab GTPase that plays a critical role in synaptic vesicle recycling and neurotransmitter release. It is expressed in the brain and is involved in the regulation of synaptic function and plasticity. Mutations in the Rab27abound gene can lead to neurological disorders, highlighting its importance in brain function.
