General annotation (Comments)

Function

Endoglycosidase that cleaves heparan sulfate proteoglycans (HSPGs) into heparan sulfate side chains and core proteoglycans. Participates in extracellular matrix (ECM) degradation and remodeling By similarity. Increases cell adhesion to the extacellular matrix (ECM), independent of its enzymatic activity. Ref.2

Subunit structure

Heterodimer; the active enzyme is a heterodimer of the 60 kDa and 45 kDa proteolytic products. Ref.1

Subcellular location

Secreted. Note: Localized close to cell surface. Ref.1

Developmental stage

Expressed, as early as 12 h post fertilization, in cells migrating from the epiblast and forming the hypoblast layer. Later on at 72 h, preferentially expressed in cells of the developing vascular and nervous systems. Ref.1

Post-translational modification

N-glycosylated By similarity.

Proteolytically cleaved to produce a 60 kDa and a 45 kDa product.

Sequence similarities

Belongs to the glycosyl hydrolase 79 family.
