Ubiquitin code assembly and disassembly
Ubiquitin, a 76 amino-acid polypeptide, presents a compact three-dimensional structure, utilising a fold that recurs within larger polypeptides and in other protein modifiers, such as NEDD8 and SUMO. Ubiquitylation was initially recognised as a signal for proteasome-mediated degradation. We shall consider here how this view has evolved to appreciate that the dynamic appendage of different types...
متن کاملDistinct Annular Oligomers Captured along the Assembly and Disassembly Pathways of Transthyretin Amyloid Protofibrils
BACKGROUND Defects in protein folding may lead to severe degenerative diseases characterized by the appearance of amyloid fibril deposits. Cytotoxicity in amyloidoses has been linked to poration of the cell membrane that may involve interactions with amyloid intermediates of annular shape. Although annular oligomers have been detected in many amyloidogenic systems, their universality, function ...
متن کاملMechanisms of Synapse Assembly and Disassembly
The mechanisms that govern synapse formation and elimination are fundamental to our understanding of neural development and plasticity. The wiring of neural circuitry requires that vast numbers of synapses be formed in a relatively short time. The subsequent refinement of neural circuitry involves the formation of additional synapses coincident with the disassembly of previously functional syna...
متن کاملAssembly and disassembly of DNA polymerase holoenzyme.
The complex task of genomic replication requires a large collection of proteins properly assembled within the close confines of the replication fork. The mechanism and dynamics of holoenzyme assembly and disassembly have been investigated using steady state and pre-steady state methods as opposed to structural studies, primarily due to the intrinsic transient nature of these protein complexes d...
متن کاملMicrotubule assembly and disassembly at alkaline pH
Although it is now apparent that the intracellular pH may rise considerably above neutrality under physiological conditions, information on the effect of alkaline pH on microtubule assembly and disassembly is still quite fragmentay. We have studied the assembly/disassembly of bovine brain microtubule protein at alkaline pH in vitro. When microtubules are assembled to a new steady state at pH le...
