Ubiquitin and ubiquitin-like conjugates
The ubiquitin system remains elusive as a wide variety of post-translational modifications - including ubiquitylation with longer ubiquitin chains - are possible. Although the ubiquitin building block stays the same, different chain linkage types can result in different cellular processes. To understand the similarities and differences of these chains, a meticulous look at the intricate dynamics is absolutely necessary.
We perform molecular dynamics simulations of a variety of di-/tri- and tetra-ubiquitin chains using different resolution scales and bridge the gap between experimental studies and in silico methods by various cooperations.
