FunctionCollagen type III occurs in most soft connective tissues along with type I collagen.
Involvement in diseaseDefects in COL3A1 are a cause of Ehlers-Danlos syndrome type 3 (EDS3) [MIM:130020]; also known as benign hypermobility syndrome. EDS is a connective tissue disorder characterized by hyperextensible skin, atrophic cutaneous scars due to tissue fragility and joint hyperlaxity. EDS3 is a form of Ehlers-Danlos syndrome characterized by marked joint hyperextensibility without skeletal deformity.
Defects in COL3A1 are the cause of Ehlers-Danlos syndrome type 4 (EDS4) [MIM:130050]. EDS is a connective tissue disorder characterized by hyperextensible skin, atrophic cutaneous scars due to tissue fragility and joint hyperlaxity. EDS4 is the most severe form of the disease. It is characterized by the joint and dermal manifestations as in other forms of the syndrome, characteristic facial features (acrogeria) in most patients, and by proneness to spontaneous rupture of bowel and large arteries. The vascular complications may affect all anatomical areas.
Defects in COL3A1 are a cause of susceptibility to aortic aneurysm abdominal (AAA) [MIM:100070]. AAA is a common multifactorial disorder characterized by permanent dilation of the abdominal aorta, usually due to degenerative changes in the aortic wall. Histologically, AAA is characterized by signs of chronic inflammation, destructive remodeling of the extracellular matrix, and depletion of vascular smooth muscle cells.
Sequence similaritiesBelongs to the fibrillar collagen family.
Contains 1 fibrillar collagen NC1 domain.
Contains 1 VWFC domain.
modificationsProline residues at the third position of the tripeptide repeating unit (G-X-Y) are hydroxylated in some or all of the chains.
O-linked glycan consists of a Glc-Gal disaccharide bound to the oxygen atom of a post-translationally added hydroxyl group.
Cellular localizationSecreted > extracellular space > extracellular matrix.
- Information by UniProt
All lanes : Anti-Collagen III antibody [FH-7A] (ab6310) at 1/500 dilution
Lane 1 : plus ab7535 reduced and denatured
Lane 2 : plus ab7535 native
All lanes : Goat anti-mouse-HRP at 1/2000 dilution
The protein can be used reduced + denaturated (band size ~130 kDa) or native (two bands ~ 130kDa and ~300kDa) The native protein gives a brighter signal.PH of the protein lysate is low - a loading dye with bromphenolblue changes its colour. This does not effect the western blot.
