abstract = {Intrinsically disordered proteins (IDPs) can be degraded in
a ubiquitin-independent process by the 20S proteasome.
Decline in 20S activity characterizes neurodegenerative
diseases. Here, we examine 20S degradation of IDP tau, a
protein that aggregates into insoluble deposits in
Alzheimer’s disease. We show that cleavage of tau by the
20S proteasome is most efficient within the
aggregation-prone repeat region of tau and generates both
short, aggregation-deficient peptides and two long fragments
containing residues 1 to 251 and 1 to 218. Phosphorylation
of tau by the non-proline–directed
Ca2+/calmodulin-dependent protein kinase II inhibits
degradation by the 20S proteasome. Phosphorylation of tau by
GSK3β, a major proline-directed tau kinase, modulates tau
degradation kinetics in a residue-specific manner. The study
provides detailed insights into the degradation products of
tau generated by the 20S proteasome, the residue specificity
of degradation, single-residue degradation kinetics, and
their regulation by posttranslational modification.},
