We then investigated the function of FK506-binding protein (FKBP) 12, which is known to accumulate in neurofibrillary tangles in vivo, on aggregation of the R3 peptide and found that FKBP12 completely prevented the peptide from aggregating at a concentration ratio of 1 : 4 (peptide:FKBP12). FKBP12 also restored the oligomer of the peptide to its monomeric status. Mutational studies on the catalytic center of FKBP12 indicated that peptidyl-prolyl isomerase activity of FKBP12 was essential for prevention of aggregation. Assuming that the propensity of aggregation of the peptide is different in each cis-/trans-isomer, we propose that the aggregation behavior of the R3 peptide can be theoretically described with a simple kinetic scheme, in which only the cis-isomer can aggregate and FKBP12 catalyzes isomerization of the peptide in both the monomeric and aggregative states.
