Correction: Nanoscale protein architecture of the kidney glomerular basement membrane

Nanoscale protein architecture of the kidney glomerular basement membrane

In multicellular organisms, proteins of the extracellular matrix (ECM) play structural and functional roles in essentially all organs, so understanding ECM protein organization in health and disease remains an important goal. Here, we used sub-diffraction resolution stochastic optical reconstruction microscopy (STORM) to resolve the in situ molecular organization of proteins within the kidney g...

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...
