Gdi1 Protein is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
GDI1 Protein (GDP Dissociation Inhibitor 1) is a key regulator of Rab GTPases, essential for controlling vesicle trafficking in neurons. It plays critical roles in synaptic vesicle cycling, neurotransmitter release, and membrane trafficking throughout the neuron. [1]
