General annotation (Comments)

Function

Cleaves the propeptides of type I and II collagen prior to fibril assembly. Does not act on type III collagen. May also play a role in development that is independent of its role in collagen biosynthesis.

Catalytic activity

Cleaves the N-propeptide of collagen chain alpha-1(I) at Pro-|-Gln and of alpha-1(II) and alpha-2(I) at Ala-|-Gln.

Cofactor

Binds 1 zinc ion per subunit By similarity.

Subunit structure

May belong to a multimeric complex. Binds specifically to collagen type XIV By similarity.

Subcellular location

Secreted › extracellular space › extracellular matrixBy similarity.

Tissue specificity

Expressed at high level in skin, bone, tendon and aorta and at low levels in thymus and brain.

Domain

The spacer domain and the TSP type-1 domains are important for a tight interaction with the extracellular matrix.

Post-translational modification

The precursor is cleaved by a furin endopeptidase By similarity.

Involvement in disease

Defects in ADAMTS2 are the cause of Ehlers-Danlos syndrome type 7C (EDS7C) [MIM:225410]. EDS is a connective tissue disorder characterized by hyperextensible skin, atrophic cutaneous scars due to tissue fragility and joint hyperlaxity. EDS7C is marked by extremely fragile tissues, hyperextensible skin and easy bruising. Facial skin contains numerous folds, as in the cutis laxa syndrome.

Sequence similarities

Contains 1 disintegrin domain.

Contains 1 peptidase M12B domain.

Contains 1 PLAC domain.

Contains 4 TSP type-1 domains.

Caution

Has sometimes been referred to as ADAMTS3.
