Sialidase 1 (lysosomal sialidase), also known as NEU1 is a mammalian lysosomal neuraminidase enzyme which in humans is encoded by the NEU1 gene. The protein encoded by this gene encodes the lysosomal enzyme, which cleaves terminal sialic acid residues from substrates such as glycoproteins and glycolipids. In the lysosome, this enzyme is part of a heterotrimeric complex together with beta-galactosidase and cathepsin A (the latter also referred to as 'protective protein'). Mutations in this gene can lead to sialidosis. Deficiencies in the human enzyme NEU1 leads to sialidosis, a rare lysosomal storage disease. Sialidase has also been shown to enhance recovery from spinal cord contusion injury when injected in rats. NEU1 has been shown to interact with Cathepsin A.
