Protein existenceEvidence at transcript level

General annotation (Comments)

Function

Hydrolyzes sialylated compounds.

Catalytic activity

Hydrolysis of alpha-(2->3)-, alpha-(2->6)-, alpha-(2->8)- glycosidic linkages of terminal sialic acid residues in oligosaccharides, glycoproteins, glycolipids, colominic acid and synthetic substrates.

Subcellular location

Cytoplasm.

Tissue specificity

Highly expressed in heart.

Sequence similarities

Belongs to the glycosyl hydrolase 33 family.

Contains 2 BNR repeats.

Sequence caution

The sequence BAB39152.1 differs from that shown. Reason: Erroneous initiation.
