Anti-Collagen, Type V, alpha 3 antibodies enable researchers to detect and measure the Collagen, Type V, alpha 3 antigen in biological samples. This target is a reported synonym of the COL5A3 gene, which encodes collagen type V alpha 3 chain. This protein is known to function in cell matrix adhesion and extracellular matrix organization, among other biological roles. The human version of Collagen, Type V, alpha 3 has a canonical amino acid length of 1745 residues and a protein mass of 172.1 kilodaltons. It is reported to be localized in the extracellular matrix and is secreted of cells and widely expressed in many tissue types. Other names for this target antigen include collagen alpha-3(V) chain and collagen, type V, alpha 3.
