Predicted to enable exo-alpha-(2->3)-sialidase activity and exo-alpha-(2->8)-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 cytoplasm; intracellular membrane-bounded organelle; and membrane. Orthologous to human NEU3 (neuraminidase 3). [provided by Alliance of Genome Resources, Apr 2022]
