The perennial organelle: assembly and disassembly of the primary cilium.
Primary cilia contain signaling receptors of diverse classes, and ciliary dysfunction results in a variety of developmental defects. Thus, primary cilia are thought to have an important role in sensing and transducing cellular signals. Although there is clear evidence demonstrating that these organelles are assembled and disassembled dynamically as cells progress through the cell cycle, the mec...
متن کاملUbiquitin 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 کاملCPAP promotes timely cilium disassembly to maintain neural progenitor pool
A mutation in the centrosomal-P4.1-associated protein (CPAP) causes Seckel syndrome with microcephaly, which is suggested to arise from a decline in neural progenitor cells (NPCs) during development. However, mechanisms ofNPCs maintenance remain unclear. Here, we report an unexpected role for the cilium inNPCs maintenance and identifyCPAPas a negative regulator of ciliary length independent of ...
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...
