Nptx1 Gene Summary [Rat]
Predicted to enable metal ion binding activity. Involved in several processes, including mitochondrial fragmentation involved in apoptotic process; neurotransmitter receptor localization to postsynaptic specialization membrane; and postsynaptic density assembly. Is active in glutamatergic synapse and synaptic cleft. Human ortholog(s) of this gene implicated in autosomal dominant cerebellar ataxia. Orthologous to human NPTX1 (neuronal pentraxin 1).

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 Nptx1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
