Lin7a Gene Summary [Rat]
Enables PDZ domain binding activity. Predicted to be involved in neurotransmitter secretion; regulation of synaptic assembly at neuromuscular junction; and synaptic vesicle transport. Predicted to act upstream of or within inner ear development. Located in basolateral plasma membrane. Is active in synapse. Orthologous to human LIN7A (lin-7 homolog A, crumbs cell polarity complex component). [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 Lin7a often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
