Myo9a Gene Summary [Rat]
Predicted to enable actin filament binding activity and microfilament motor activity. Predicted to be involved in several processes, including establishment of epithelial cell apical/basal polarity; postsynaptic specialization organization; and regulation of neuron projection arborization. Is active in glutamatergic synapse and postsynapse. Human ortholog(s) of this gene implicated in congenital myasthenic syndrome. Orthologous to human MYO9A (myosin IXA).

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 Myo9a often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
