Nptn Gene Summary [Mouse]
Predicted to enable cell-cell adhesion mediator activity; transmembrane transporter binding activity; and type 1 fibroblast growth factor receptor binding activity. Involved in intracellular calcium ion homeostasis and negative regulation of cytokine production. Acts upstream of or within excitatory synapse assembly; modulation of chemical synaptic transmission; and regulation of receptor localization to synapse. Located in immunological synapse. Is expressed in several structures, including cardiovascular system; genitourinary system; gut; nervous system; and respiratory system. Orthologous to human NPTN (neuroplastin).

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