Neu3 Gene Summary [Rat]
Predicted to enable exo-alpha-sialidase activity. Predicted to be involved in several processes, including ganglioside catabolic process; negative regulation of clathrin-dependent endocytosis; and positive regulation of epidermal growth factor receptor signaling pathway. Predicted to act upstream of or within carbohydrate metabolic process. Predicted to be located in bounding membrane of organelle and external side of plasma membrane. Predicted to be active in lysosome and membrane. Orthologous to human NEU3 (neuraminidase 3). [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 Neu3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
