BRCA1 Is a Histone-H2A-Specific Ubiquitin Ligase [PDF]
Cell Reports, 2014 The RING domain proteins BRCA1 and BARD1 comprise a heterodimeric ubiquitin (E3) ligase that is required for the accumulation of ubiquitin conjugates at sites of DNA damage and for silencing at DNA satellite repeat regions. Despite its links to chromatin,

Cryo-EM structure of the human COP1-DET1 ubiquitin ligase complex [PDF]
Nature CommunicationsUbiquitin modifications regulate fundamental cellular activities by modulating protein stability and function. The ubiquitin ligase COP1, which is present across species from plants to humans, plays a crucial role in the ubiquitination of developmental ...

Structural Diversity of Ubiquitin E3 Ligase
Molecules, 2021 The post-translational modification of proteins regulates many biological processes. Their dysfunction relates to diseases. Ubiquitination is one of the post-translational modifications that target lysine residue and regulate many cellular processes ...

HERC Ubiquitin Ligases in Cancer [PDF]
Cancers, 2020 HERC proteins are ubiquitin E3 ligases of the HECT family. The HERC subfamily is composed of six members classified by size into large (HERC1 and HERC2) and small (HERC3–HERC6). HERC family ubiquitin ligases regulate important cellular processes, such as neurodevelopment, DNA damage response, cell proliferation, cell migration, and immune responses ...

Emerging roles of the HECT E3 ubiquitin ligases in gastric cancer
Pathology and Oncology Research, 2023 Gastric cancer (GC) is one of the most pernicious gastrointestinal tumors with extraordinarily high incidence and mortality. Ubiquitination modification of cellular signaling proteins has been shown to play important roles in GC tumorigenesis ...

Activity-based probe profiling of RNF12 E3 ubiquitin ligase function in Tonne-Kalscheuer syndrome
Life Science Alliance, 2022 The authors use photocrosslinking activity-based probes to monitor RNF12/RLIM E3 ubiquitin ligase activity and report the impact of Tonne-Kalscheuer syndrome (TOKAS) patient variants on catalysis.

Ubiquitin-protein ligases [PDF]
Journal of Cell Science, 2004 Post-translational covalent tagging of proteins with the 76-residue protein ubiquitin (Ub) serves many functions. Polyubiquitylated proteins are directed to the large multi-component, multi-catalytic protease the 26S proteasome.

Ubiquitin ligases and beyond [PDF]
BMC Biology, 2012 In a review published in 2004 [1] and that still repays reading today, Cecile Pickart traced the evolution of research on ubiquitination from its origins in the proteasomal degradation of proteins through the revelation that it has a central role in cell cycle regulation and the recognition of regulatory roles for ubiquitin in intracellular membrane ...

Biomolecules, 2021 Cellular homeostasis depends on robust protein quality control (PQC) pathways that discern misfolded proteins from functional ones in the cell. One major branch of PQC involves the controlled degradation of misfolded proteins by the ubiquitin-proteasome ...

Ubiquitin ligase activity inhibits Cdk5 to control axon termination.
PLoS Genetics, 2022 The Cdk5 kinase plays prominent roles in nervous system development, plasticity, behavior and disease. It also has important, non-neuronal functions in cancer, the immune system and insulin secretion.
