abstract = {The protein folding problem was apparently solved recently
by the advent of a deep learning method for protein
structure prediction called AlphaFold. However, this program
is not able to make predictions about the protein folding
pathways. Moreover, it only treats about half of the human
proteome, as the remaining proteins are intrinsically
disordered or contain disordered regions. By definition
these proteins differ from natively folded proteins and do
not adopt a properly folded structure in solution. However
these intrinsically disordered proteins (IDPs) also
systematically differ in amino acid composition and uniquely
often become folded upon binding to an interaction partner.
These factors preclude solving IDP structures by current
machine-learning methods like AlphaFold, which also cannot
solve the protein aggregation problem, since this
meta-folding process can give rise to different aggregate
sizes and structures. An alternative computational method is
provided by molecular dynamics simulations that already
successfully explored the energy landscapes of IDP
conformational switching and protein aggregation in multiple
cases. These energy landscapes are very different from those
of ‘simple’ protein folding, where one energy funnel
leads to a unique protein structure. Instead, the energy
landscapes of IDP conformational switching and protein
aggregation feature a number of minima for different
competing low-energy structures. In this review, I discuss
the characteristics of these multifunneled energy landscapes
in detail, illustrated by molecular dynamics simulations
that elucidated the underlying conformational transitions
and aggregation processes.},
