Protein attributes

Sequence length	322 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)

Function	May have a role in bone formation and also in establishing the ordered structure of cartilage through matrix organization.
Subcellular location	Secreted › extracellular space › extracellular matrix By similarity.
Tissue specificity	Cartilage, ligament, and placenta. Ref.1
Post-translational modification	The O-linked polysaccharides on Thr-60 and Ser-96 are probably the mucin type linked to GalNAc. There is one glycosaminoglycan chain, known to be dermatan sulfate, and it is probably the O-glycosylation at Ser-64 By similarity.
Sequence similarities	Belongs to the small leucine-rich proteoglycan (SLRP) family. SLRP class III subfamily. Contains 6 LRR (leucine-rich) repeats. Contains 1 LRRNT domain.
