Rab11A Protein (Ras Related Protein Rab 11A) is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
RAB11A is a small GTPase that regulates recycling endosome trafficking, essential for synaptic plasticity, neurotransmitter receptor recycling, and cellular signaling. It controls the return of receptors and vesicles to the plasma membrane.
Structure
RAB11A is a 216-amino acid GTPase:
Switch I/II regions for GTP binding
C-terminal geranylgeranylation for membrane association
Multiple effector binding sites
Normal Function
Recycling Endosome Function
Receptor recycling: Controls AMPA, [NMDA](/entities/nmda-receptor), GABA receptor return to membrane<sup>[1]</sup>
Synaptic plasticity: Essential for activity-dependent modifications
