SCF E3 Ligase Substrates Switch from CAN-D to Can-ubiquitylate

open access: yes, 2018
Liu et al. (2018) report a mathematical model predicting how the cellular repertoire of SCF E3 ligases is assembled by “adaptive exchange on demand,” with the limited pool of CUL1 scanning the vast sea of F-box proteins for those with substrates ...

Transcriptome dynamics in the asexual cycle of the chordate Botryllus schlosseri [PDF]

open access: yes, 2016
Background: We performed an analysis of the transcriptome during the blastogenesis of the chordate Botryllus schlosseri, focusing in particular on genes involved in cell death by apoptosis. The tunicate B.

Molecular Mechanisms of Extracellular Vesicle Biogenesis and Their Impact on the Design of Custom EVs

open access: yesAdvanced Healthcare Materials, EarlyView.
Extracellular vesicles (EVs) are pivotal mediators of intercellular communication and disease, yet the fundamental mechanisms controlling their biogenesis and cargo selection remain unclear. This limitation hinders their diagnostic utility and therapeutic development.

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 ...

A Tobacco Homolog of DCN1 is Involved in Cellular Reprogramming and in Developmental Transitions [PDF]

open access: yes, 2011
Plant proteomes show remarkable plasticity in reaction to environmental challenges and during developmental transitions. Some of this adaptability comes from ubiquitin-mediated protein destruction regulated by cullin-RING E3 ubiquitin ligases (CRLs ...

The E3 ligase TRIM22 restricts SARS-CoV-2 replication by promoting proteasomal degradation of NSP8

open access: yesmBio
Replication of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) genome is mediated by a complex of non-structural proteins (NSPs), of which NSP7 and NSP8 serve as subunits and play a key role in promoting the activity of RNA-dependent RNA ...

Conversion of a DNA ligase into an RNA capping enzyme [PDF]

open access: yesNucleic Acids Research, 1999
In eukaryotes, newly synthesised mRNA is 'capped' by the addition of GMP to the 5" end by RNA capping enzymes. Recent structural studies have shown that RNA capping enzymes and DNA ligases have similar protein folds, suggesting a conserved catalytic mechanism.
