Structural studies of the coiled-coil domain of TRIM75 reveal a tetramer architecture facilitating its E3 ligase complex

open access: yesComputational and Structural Biotechnology Journal, 2022
Protein ubiquitination plays a vital role in controlling the degradation of intracellular proteins and in regulating cell signaling pathways. Functionally, E3 ubiquitin ligases control the transfer of ubiquitin to the target substrates. As a major family

Peptide Display Directed Assembly of Biopolymer Core–Silica Shell Particles

open access: yesAdvanced Healthcare Materials, EarlyView.
Bacterial cells are engineered to produce biopolyester particles displaying peptides mediating growth of silica. Peptide‐coated biopolyester particles are treated with silica precursors and silica shell formation is studied. Transmission electron microscopy shows silica‐coated BPs which are formed after the silicification treatment. Characterization of

Obscurin and KCTD6 regulate cullin-dependent small ankyrin-1 (sAnk1.5) protein turnover. [PDF]

open access: yes, 2012
Protein turnover through cullin-3 is tightly regulated by posttranslational modifications, the COP9 signalosome, and BTB/POZ-domain proteins that link cullin-3 to specific substrates for ubiquitylation.

Ubiquitin Ligation without a Ligase [PDF]

open access: yesDevelopmental Cell, 2007
Classically, ubiquitination requires three enzymes acting in sequence: E1, E2, and E3. E3 ubiquitin ligases typically provide substrate specificity. An article in Molecular Cell (Hoeller et al., 2007) now describes the E3-independent monoubiquitination of certain proteins. The mechanism has interesting parallels to SUMO ligation.

An Organ‐on‐Chip Platform for Strain‐Controlled, Tissue‐Specific Compression of Cartilage and Mineralized Osteochondral Interface to Study Mechanical Overloading in Osteoarthritis

open access: yesAdvanced Healthcare Materials, EarlyView.
A mechanically active OsteoChondral Unit (OCU)‐on‐Chip platform mimicking the OCU's functional anatomy and the strain gradient across the osteochondral interface is presented. Upon compartment‐specific hyperphysiological compression, the model replicates mechanisms observed in osteoarthritis (OA) progression, such as calcium crystal accumulation ...

The COP9 SIGNALOSOME is required for postembryonic meristem maintenance in Arabidopsis thaliana [PDF]

open access: yes, 2015
Cullin-RING E3 ligases (CRLs) regulate different aspects of plant development, and are activated by modification of their cullin subunit with the ubiquitin-like protein NEDD8 (NEural precursor cell expressed Developmentally Down-regulated 8) (neddylation)

High‐Resolution Patterned Delivery of Chemical Signals From 3D‐Printed Picoliter Droplet Networks

open access: yesAdvanced Materials, EarlyView.
3D‐printed picoliter droplet networks have been fabricated that control gene expression in bacterial populations by releasing chemical signals with precise spatial definition and high temporal resolution. This system of effector release is widely applicable, offering diverse applications in biology and medicine.

Charting the protein complexome in yeast by mass spectrometry [PDF]

open access: yes, 2002
It has become evident over the past few years that many complex cellular processes, including control of the cell cycle and ubiquitin-dependent proteolysis, are carried out by sophisticated multisubunit protein machines that are dynamic in abundance ...
