Background

Collagen III alpha 1, also referred to as collagen type III alpha 1 or COL3A1 for short, was first described in 1971 and is a member of the collagen superfamily and encoded COL3A1 gene (1, 2). In general, collagen III is an extracellular matrix protein that is synthesized as a preprocollagen followed by cleaving of the signal peptide to form the procollagen (1). The human COL3A1 gene is located on chromosome 2q32.2 and collagen III is synthesized as a homotrimer consisting of three identical alpha procollagen chains which are stabilized by disulfide bonds (1,2,3). Each alpha chain is 1466 amino acids (aa) in length with a theoretical molecular weight of 139 kDa for a single alpha chain (1). Structurally, each alpha chain is a left-handed helix which then join together to form a right-handed triple helix (1,2). C-terminal and N-terminal proteinases remove the globular ends of the procollagen to form the type III collagen (1).

Collagen III is a fibrillar collagen that constitutes 5-20% of all collagen in the body (1). It provides structural integrity and is found in many hallow organs and soft connective tissue including the vascular system, skin, lung, uterus, and intestine (1,2). Additionally, collagen III has be found to be associated with type I collagen in the same fibrils (1). Collagen III interacts with signaling integrins to carry out other key functions including cell adhesion, proliferation, and differentiation (1).

Mutations in the COL3A1 gene has been associated with a variety of human diseases, the most well-known being a group of connective tissue disorders termed Ehlers-Danlos Syndromes (1,2,4). Vascular Ehlers-Danlos Syndrome is a specific subtype that is considered the most severe and although the clinical manifestations vary, symptoms include thin skin and fragile blood vessels and can often result in both lung and heart complications (1,4). COL3A1 is also associated with glomerulopathies, or diseases of the glomeruli, which are characterized by an abundance of extracellular matrix (3). Collagenofibrotic glomerulopathy is one specific rare renal disease that is characterized by excessive levels of collagen III (3).

FAQs for Collagen III alpha 1/COL3A1 Recombinant Protein (H00001281-P01). (Showing 1 - 1 of 1 FAQ).

1. I'm interested in using colagen III in adhesion assays of cell lines to collagen-coated TC plates. I've seen you have human recombinant collagen III (H00001281-P01) but in the datasheet it says it is not suitable for functional assays. I was wondering, though, if it is OK to use it in adhesion assays. You also have non-recombinant collagen III (NBP1-97267), which I guess it's purified. Is this one suitable for adhesion assays?
   • H00001281-P01 product is distributed by us through a Taiwanese company called Abnova. They do not test the activity of their recombinant proteins. The proteins are produced in a cell-free wheat germ system with an N-terminal 26kDa GST-tag. Due to this expression system, in our experience, the proteins do not always undergo the same folding and post-transnational modifications they might undergo in an endogenous cell. Because of this, we do not recommend this protein for use in functional assays and do not guarantee them for this use. They are mainly intended for use in Western Blots as a positive control with their antibody. NBP1-97267 is a native protein purified from a human source.
