Description:
This gene encodes one of the chains for type I collagen, the fibrillar collagen found in most connective tissues. Mutations in this gene are associated with osteogenesis imperfecta, Ehlers-Danlos syndrome, idiopathic osteoporosis, and atypical Marfan syndrome. Symptoms associated with mutations in this gene, however, tend to be less severe than mutations in the gene for alpha-1 type I collagen since alpha-2 is less abundant. Multiple messages for this gene result from multiple polyadenylation signals, a feature shared by most of the other collagen genes.

Research Backgrounds

Function:

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

PTMs:

Contains mostly 4-hydroxyproline. Proline residues at the third position of the tripeptide repeating unit (G-X-Y) are hydroxylated in some or all of the chains.

Contains 3-hydroxyproline at a few sites. This modification occurs on the first proline residue in the sequence motif Gly-Pro-Hyp, where Hyp is 4-hydroxyproline.

Lysine residues at the third position of the tripeptide repeating unit (G-X-Y) are 5-hydroxylated in some or all of the chains.

O-glycosylated on hydroxylated lysine residues. The O-linked glycan consists of a Glc-Gal disaccharide.

Subcellular Location:

Secreted>Extracellular space>Extracellular matrix.

Extracellular region or secreted Cytosol Plasma membrane Cytoskeleton Lysosome Endosome Peroxisome ER Golgi apparatus Nucleus Mitochondrion Manual annotation Automatic computational assertionSubcellular location
Tissue Specificity:

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

Subunit Structure:

Trimers of one alpha 2(I) and two alpha 1(I) chains. Interacts with MRC2 (By similarity). Interacts with TRAM2. Interacts with MFAP4 in a Ca (2+)-dependent manner (By similarity).

Family&Domains:

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).

Belongs to the fibrillar collagen family.
