Protein attributes

Sequence length	680 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Type X collagen is a product of hypertrophic chondrocytes and has been localized to presumptive mineralization zones of hyaline cartilage.
Subunit structure	Homotrimer.
Subcellular location	Secreted › extracellular space › extracellular matrix By similarity.
Post-translational modification	Prolines at the third position of the tripeptide repeating unit (G-X-Y) are hydroxylated in some or all of the chains.
Involvement in disease	Schmid type metaphyseal chondrodysplasia (SMCD) [MIM:156500]: Dominantly inherited disorder of the osseous skeleton. The cardinal features of the phenotype are mild short stature, coxa vara and a waddling gait. Radiography usually shows sclerosis of the ribs, flaring of the metaphyses, and a wide irregular growth plate, especially of the knees. A variant form of SMCD is spondylometaphyseal dysplasia Japanese type. It is characterized by spinal involvement comprising mild platyspondyly, vertebral body abnormalities, and end-plate irregularity. Note: The disease is caused by mutations affecting the gene represented in this entry. Ref.12 Ref.13 Ref.14 Ref.15 Ref.16 Ref.17 Ref.19 Ref.20
Sequence similarities	Contains 1 C1q domain.
