  • Function
    Type I collagen is a member of group I collagen (fibrillar forming collagen).
  • Tissue specificity
    Forms the fibrils of tendon, ligaments and bones. In bones the fibrils are mineralized with calcium hydroxyapatite.
  • Involvement in disease
    Ehlers-Danlos syndrome 7B
    Osteogenesis imperfecta 1
    Osteogenesis imperfecta 2
    Ehlers-Danlos syndrome, autosomal recessive, cardiac valvular form
    Osteogenesis imperfecta 3
    Osteogenesis imperfecta 4
    A chromosomal aberration involving COL1A2 may be a cause of lipoblastomas, which are benign tumors resulting from transformation of adipocytes, usually diagnosed in children. Translocation t(7;8)(p22;q13) with PLAG1.
  • Sequence similarities
    Belongs to the fibrillar collagen family.
    Contains 1 fibrillar collagen NC1 domain.
  • 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.
  • Post-translational
    Prolines at the third position of the tripeptide repeating unit (G-X-Y) are hydroxylated in some or all of the chains.
  • Cellular localization
    Secreted > extracellular space > extracellular matrix.
