Detergent-prepared glomerular basement membrane is composed of a heterogeneous group of polypeptides.

Bovine Glomerular Basement Membrane

The collagenous domain of bovine glomerular basement membrane was excised in soluble form by limited pepsin digestion and characterized. The domain amounts to approximately 25% of the whole membrane by weight. The constituent polypeptides were studied using several electrophoresis systems and amino acid analysis. The electrophoresis systems used were a combination of agarose and polyacrylamide...

Glomerular Basement Membrane

The noncollagenous domain hexamer of collagen IV from bovine glomerular basement membrane was further investigated to determine the types of collagen chain from which subunits M2*b and M3 are derived. M2*b was shown to be a shorter form, containing 9 fewer residues, of M2*a which was previously established as the noncollagenous domain of a third chain, a3, of collagen IV (Saus, J., Wieslander, ...

Anti-glomerular basement membrane antibodies.

Basement membranes form an anatomic barrier that contains connective tissue. They are composed of type IV collagen, laminin and proteoglycans. Anti-basement membrane antibodies bind to the non-collagen site of the α3 chain of type IV collagen. A group of renal diseases, pulmonary diseases and perhaps others affecting different organs have long been associated with the presence of antibodies dir...

Anti-Glomerular Basement Membrane Disease.

Anti-glomerular basement membrane (anti-GBM) disease is a rare small vessel vasculitis that affects the capillary beds of the kidneys and lungs. It is an archetypic autoimmune disease, caused by the development of directly pathogenic autoantibodies targeting a well characterized autoantigen expressed in the basement membranes of these organs, although the inciting events that induce the autoimm...
