COL5A1
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).
Function
Type V collagen is a member of group I collagen (fibrillar forming collagen). It is a minor connective tissue component of nearly ubiquitous distribution. Type V collagen binds to DNA, heparan sulfate, thrombospondin, heparin, and insulin.
Involvement in disease
Ehlers-Danlos syndrome, classic type, 1
EDSCL1
A form of Ehlers-Danlos syndrome, a group of connective tissue disorders characterized by skin hyperextensibility, articular hypermobility, and tissue fragility. The main features of classic Ehlers-Danlos syndrome are joint hypermobility and dislocation, and fragile, bruisable skin. EDSCL1 inheritance is autosomal dominant.
None
The disease is caused by variants affecting the gene represented in this entry.
Fibromuscular dysplasia, multifocal
FMDMF
An autosomal dominant vascular disorder with incomplete penetrance, characterized by fibrous tissue and webs developing in the artery wall and leading to multiple arterial stenoses. Patients with multifocal fibromuscular dysplasia can develop arterial tortuosity, macroaneurysms, and dissections. Arterial rupture may occur.
None
The disease is caused by variants affecting the gene represented in this entry.
Post-translational modifications
Prolines at the third position of the tripeptide repeating unit (G-X-Y) are hydroxylated in some or all of the chains.
Sulfated on 40% of tyrosines.
Sequence Similarities
Belongs to the fibrillar collagen family.
Cellular localization
- Secreted
- Extracellular space
- Extracellular matrix
Alternative names
Collagen alpha-1(V) chain, COL5A1
