PLG and ganglioneuroma: NAPlr is a nephritogenic protein that was originally isolated from group A streptococcus and shows high homology in nucleotide and amino acid sequences to streptococcal plasmin receptor.[12,13] NAPlr induces glomerular damages by trapping plasmin and maintaining its activity, and glomerular NAPlr deposition and related plasmin activity are usually detected in classical postinfectious GN.
