Molecular playground/beta 2 microglobulin
From Proteopedia
|
is a 12kd protein that self-assembles into amyloid fibrils in the presence of copper. This reaction is considered a likely cause for dialysis related amyloidosis; a disease where these fibrils build up in joints causing pain and eventually necessitating joint replacement.
The proposed mechanism for formation is that the copper binds near the N-terminus of the protein, this binding causes structural shifts throughout, creating two new planes. These planes interact in an antiparallel fashion to form the dimer.
