[https://www.uniprot.org/uniprot/CO3A1_HUMAN CO3A1_HUMAN] Defects in COL3A1 are a cause of Ehlers-Danlos syndrome type 3 (EDS3) [MIM:[https://omim.org/entry/130020 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.<ref>PMID:7833919</ref> Defects in COL3A1 are the cause of Ehlers-Danlos syndrome type 4 (EDS4) [MIM:[https://omim.org/entry/130050 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.<ref>PMID:1370809</ref> <ref>PMID:8411057</ref> <ref>PMID:2492273</ref> <ref>PMID:7749417</ref> <ref>PMID:1352273</ref> <ref>PMID:2808425</ref> <ref>PMID:1895316</ref> <ref>PMID:1357232</ref> <ref>PMID:1496983</ref> <ref>PMID:8098182</ref> [:]<ref>PMID:7912131</ref> <ref>PMID:8019562</ref> [:]<ref>PMID:8680408</ref> <ref>PMID:8884076</ref> <ref>PMID:9147870</ref> <ref>PMID:8664902</ref> <ref>PMID:8990011</ref> <ref>PMID:9036918</ref> <ref>PMID:9452103</ref> <ref>PMID:10923041</ref> <ref>PMID:10706896</ref> <ref>PMID:11168790</ref> <ref>PMID:12694234</ref> <ref>PMID:12786757</ref> Defects in COL3A1 are a cause of susceptibility to aortic aneurysm abdominal (AAA) [MIM:[https://omim.org/entry/100070 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.<ref>PMID:8514866</ref> <ref>PMID:2243125</ref> <ref>PMID:2349939</ref>

== Publication Abstract from PubMed ==
 +
Procollagen C-proteinase enhancer-1 (PCPE-1) is a secreted protein that specifically accelerates proteolytic release of the C-propeptides from fibrillar procollagens, a crucial step in fibril assembly. As such, it is a potential therapeutic target to improve tissue repair and prevent fibrosis, a major cause of mortality worldwide. Here we present the crystal structure of the active CUB1CUB2 fragment of PCPE-1 bound to the C-propeptide trimer of procollagen III (CPIII). This shows that the two CUB domains bind to two different chains of CPIII and that the N-terminal region of one CPIII chain, close to the proteolytic cleavage site, lies in the cleft between CUB1 and CUB2. This suggests that enhancing activity involves unraveling of this chain from the rest of the trimer, thus facilitating the action of the proteinase involved. Support for this hypothesis comes from site-directed mutagenesis, enzyme assays, binding studies, and molecular modeling.
