Rab8a Gene Summary [Rat]
Enables protein tyrosine kinase binding activity. Involved in several processes, including cellular response to insulin stimulus; neurotransmitter receptor transport, endosome to postsynaptic membrane; and regulation of long-term neuronal synaptic plasticity. Located in several cellular components, including Golgi apparatus; dendrite; and neuronal cell body. Is active in glutamatergic synapse. Orthologous to human RAB8A (RAB8A, member RAS oncogene family). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Rab8a often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
