General annotation (Comments)

Function

Type I collagen is a member of group I collagen (fibrillar forming collagen).

Subunit structure

Trimers of one alpha 2(I) and two alpha 1(I) chains.

Subcellular location

Secretedextracellular spaceextracellular matrix By similarity.

Tissue specificity

Forms the fibrils of tendon, ligaments and bones. In bones the fibrils are mineralized with calcium hydroxyapatite.

Domain

The C-terminal propeptide, also known as COLFI domain, have crucial roles in tissue growth and repair by controlling both the intracellular assembly of procollagen molecules and the extracellular assembly of collagen fibrils. It binds a calcium ion which is essential for its function 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.

Sequence similarities

Belongs to the fibrillar collagen family.

Contains 1 fibrillar collagen NC1 domain.
