CC -!- FUNCTION: Catalyzes the removal of sialic acid (N-acetylneuraminic
CC acid) moieties from glycoproteins and glycolipids. To be active, it is
CC strictly dependent on its presence in the multienzyme complex. Appears
CC to have a preference for alpha 2-3 and alpha 2-6 sialyl linkage.
CC {ECO:0000269|PubMed:9363440, ECO:0000269|PubMed:9384611}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Hydrolysis of alpha-(2->3)-, alpha-(2->6)-, alpha-
CC (2->8)- glycosidic linkages of terminal sialic acid residues in
CC oligosaccharides, glycoproteins, glycolipids, colominic acid and
CC synthetic substrates.; EC=3.2.1.18;
CC Evidence={ECO:0000269|PubMed:9363440, ECO:0000269|PubMed:9384611};
CC -!- SUBUNIT: Interacts with cathepsin A (protective protein), beta-
CC galactosidase and N-acetylgalactosamine-6-sulfate sulfatase in a
CC multienzyme complex.
CC -!- SUBCELLULAR LOCATION: Lysosome membrane {ECO:0000269|PubMed:9384611};
CC Peripheral membrane protein {ECO:0000269|PubMed:9384611}; Lumenal side
CC {ECO:0000269|PubMed:9384611}. Lysosome lumen
CC {ECO:0000269|PubMed:9384611}. Cell membrane
CC {ECO:0000269|PubMed:9384611}. Cytoplasmic vesicle
CC {ECO:0000269|PubMed:9384611}. Note=Localized not only on the inner side
CC of the lysosomal membrane and in the lysosomal lumen, but also on the
CC plasma membrane and in intracellular vesicles.
CC -!- TISSUE SPECIFICITY: Highly expressed in kidney, epididymis, followed by
CC brain, spinal cord and weakly expressed in adrenal, heart, liver, lung
CC and spleen. {ECO:0000269|PubMed:9384611}.
CC -!- DOMAIN: A C-terminal internalization signal (YGTL) appears to allow the
CC targeting of plasma membrane proteins to endosomes.
CC -!- PTM: N-glycosylated. {ECO:0000305}.
CC -!- PTM: Phosphorylation of tyrosine within the internalization signal
CC results in inhibition of sialidase internalization and blockage on the
CC plasma membrane.
CC -!- SIMILARITY: Belongs to the glycosyl hydrolase 33 family. {ECO:0000305}.
