The Proteasome and its Role in the Nervous System - PMC
WEBJul 7, 2021 · The proteasome, a multicatalytic protease complex, is a ring-like structure with a narrow pore that exhibits regulated gating, enabling the selective degradation of target proteins into peptide fragments. This process of removing proteins is essential for eliminating proteins that are no longer wanted, such as unfolded or aggregated proteins.
WEBMay 26, 2023 · The proteasome, the major protein-degradation machine in cells, regulates neuronal synapses and long-term information storage. Here, using super-resolution microscopy, we found that the two essential subcomplexes of the proteasome, the regulatory (19S) and catalytic (20S) particles, are differentially distributed within individual rat …

SUMO-SIM interactions: From structure to biological functions
WEBDec 1, 2022 · SUMO binding motifs (SBM) are short protein regions that selectively interact with SUMO in a non-covalent manner. Among the few number of SBM discovered, the most abundant type is the SUMO-Interaction Motif (SIM). A SIM is a short stretch of residues that directly interact with the SUMO surface in an extended conformation [4] (Fig. 2 A).
