Type IV collagen, the major structural component of basement membranes, is a multimeric protein composed of 3 alpha subunits. These subunits are encoded by 6 different genes, alpha 1 through alpha 6, each of which can form a triple helix structure with 2 other subunits to form type IV collagen. COL4A3 encodes alpha 3. In the Goodpasture syndrome, autoantibodies bind to the collagen molecules in the basement membranes of alveoli and glomeruli. The epitopes that elicit these autoantibodies are localized largely to the non-collagenous C-terminal domain of the protein. A specific kinase phosphorylates amino acids in this same C-terminal region and the expression of this kinase is upregulated during pathogenesis. COL4A3 is also linked to an autosomal recessive form of Alport syndrome. The mutations contributing to this syndrome are also located within the exons that encode this C-terminal region. Like the other members of the type IV collagen gene family, COL4A3 is organized in a head-to-head conformation with another type IV collagen gene so that each gene pair shares a common promoter.

The Abbkine Cleaved-Tumstatin (P1426) Rabbit Polyclonal Antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen anddetects endogenous levels of fragment of activated Tumstatin protein resulting from cleavage adjacent to P1426. The antibody has been validaed in WB, ELISA and reacts with Human, Monkey samples.
