Sialidase-1

Protein-coding gene in the species Homo sapiens From Wikipedia, the free encyclopedia

Sialidase-1, is a mammalian lysosomal neuraminidase enzyme which in humans is encoded by the NEU1 gene.[5][6]

Function

The protein SIALIDASE-1 encoded by the NEU-1 gene encodes the lysosomal enzyme SIALIDASE-1, 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.[5]

Clinical significance

Mutations in NEU1 leads to sialidosis, a rare lysosomal storage disease.[7] Sialidase has also been shown to enhance recovery from spinal cord contusion injury when injected in rats.[8]

Interactions

NEU1 has been shown to interact with Cathepsin A.[9]
