HECT E3 ubiquitin ligases – emerging insights into their biological roles and disease relevance
Homologous to E6AP C-terminus (HECT) E3 ubiquitin ligases play a critical role in various cellular pathways, including but not limited to protein trafficking, subcellular localization, innate immune response, viral infections, DNA damage responses and ...

Label-free electrochemical monitoring of DNA ligase activity [PDF]
This study presents a simple, label-free electrochemical technique for the monitoring of DNA ligase activity. DNA ligases are enzymes that catalyze joining of breaks in the backbone of DNA and are of significant scientific interest due to their essential

The α-arrestin ARRDC3 mediates ALIX ubiquitination and G protein-coupled receptor lysosomal sorting. [PDF]
The sorting of G protein-coupled receptors (GPCRs) to lysosomes is critical for proper signaling and cellular responses. We previously showed that the adaptor protein ALIX regulates lysosomal degradation of protease-activated receptor-1 (PAR1), a GPCR ...

Dynamic control of selectivity in the ubiquitination pathway revealed by an ASP to GLU substitution in an intra-molecular salt-bridge network [PDF]
Ubiquitination relies on a subtle balance between selectivity and promiscuity achieved through specific interactions between ubiquitin-conjugating enzymes (E2s) and ubiquitin ligases (E3s).

Parkin-independent mitophagy controls chemotherapeutic response in cancer cells [PDF]
Mitophagy is an evolutionarily conserved process that selectively targets impaired mitochondria for degradation. Defects in mitophagy are often associated with diverse pathologies, including cancer.

A screen for E3 ubiquitination ligases that genetically interact with the adaptor protein Cindr during Drosophila eye patterning. [PDF]
Ubiquitination is a crucial post-translational modification that can target proteins for degradation. The E3 ubiquitin ligases are responsible for recognizing substrate proteins for ubiquitination, hence providing specificity to the process of protein ...

CRL Ubiquitin Ligases and DNA Damage Response
Cullin/RING ubiquitin ligases (CRL) comprise the largest subfamily of ubiquitin ligases and are involved in various biological processes. One of the main functions of CRLs is to regulate DNA damage response, a fundamental signaling cascade to maintain ...
