Collagen alpha-1(III) chain is a protein that in humans is encoded by the COL3A1 gene[1][2], which is located on chromosome 2.

Contents

Function

Collagen alpha-1(III) chain is a fibrillar collagen that is found in extensible connective tissues such as skin, lung, and the vascular system, frequently in association with type I collagen. Although alternate transcripts have been detected for this gene, they are the result of mutations; these mutations alter splicing, often leading to the exclusion of multiple exons.[3]

Type-III collagen is a fibrous scleroprotein in bone, cartilage, tendon, bone marrow stroma and other connective tissue; yields gelatin on boiling.

Scleroprotein is a simple protein found in horny and cartilaginous tissues and in the lens of the eye.

Clinical significance

Mutations in this gene are associated with type III and IV Ehlers-Danlos syndrome and with aortic and arterial aneurysms.
