The proteasome and epigenetics: zooming in on histone modifications
The proteasome is a structural complex of many proteins that degrades substrates marked by covalent linkage to ubiquitin.Many years of research has shown a role for ubiquitin-proteasome-mediated proteolysis in synaptic plasticity and memory mainly in degrading synaptic, cytoplasmic and nuclear proteins.Recent work indicates that the proteasome has
