Protein attributes

Sequence length	1117 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at transcript level

General annotation (Comments)

Cofactor	Binds 1 zinc ion per subunit By similarity.
Subcellular location	Secreted › extracellular space › extracellular matrix By similarity.
Tissue specificity	Expressed at low levels in placenta and barely detectable in a number of other tissues.
Induction	Isoform 1 and isoform 2 expressions are up-regulated by TNF in retinal pigment epithelial cells. Ref.2 Ref.6
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. Glycosylated. Can be O-fucosylated by POFUT2 on a serine or a threonine residue found within the consensus sequence C1-X(2)-(S/T)-C2-G of the TSP type-1 repeat domains where C1 and C2 are the first and second cysteine residue of the repeat, respectively. Fucosylated repeats can then be further glycosylated by the addition of a beta-1,3-glucose residue by the glucosyltransferase, B3GALTL. Fucosylation mediates the efficient secretion of ADAMTS family members. Also can be C-glycosylated with one or two mannose molecules on tryptophan residues within the consensus sequence W-X-X-W of the TPRs, and N-glycosylated. These other glycosylations can also facilitate secretion By similarity.
Sequence similarities	Contains 1 disintegrin domain. Contains 1 peptidase M12B domain. Contains 1 PLAC domain. Contains 5 TSP type-1 domains.

Alternative products

This entry describes 4 isoforms produced by alternative splicing. [Align] [Select]

Isoform 1 (identifier: Q9UKP5-1)

Also known as: Variant 2;

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.

Isoform 2 (identifier: Q9UKP5-2)

Also known as: Variant 1;

The sequence of this isoform differs from the canonical sequence as follows:
     422-504: TKGHEAAKLM...GATSRQCKYG → RKVMKQQNYGSSHYCEYQSFFLVCLQSRFHHQLFR
     860-908: VQRQEVVCKR...CPPEWFIGDW → KMPTRQPTQR...SCNLAKETLL
     909-1117: Missing.

Note: Contains critical point mutations in the region encoding the catalytic domain as well as 2 point mutations compared with genomic sequence. May either be a rare polymorphism or may have arisen through a combination of aberrant RNA editing and point mutation/sequencing error.

Isoform 3 (identifier: Q9UKP5-3)

Also known as: Variant 3;

The sequence of this isoform differs from the canonical sequence as follows:
     457-468: DSGRGTCLDNEP → EFLKLGDSISGS
     469-1117: Missing.

Isoform 4 (identifier: Q9UKP5-4)

Also known as: Variant 4;

The sequence of this isoform differs from the canonical sequence as follows:
     283-292: AKLYRDSSLG → RLPNFTVIPA
     293-1117: Missing.
