Targeted Degradation of 53BP1 Using Ubiquitin Variant Induced Proximity
In recent years, researchers have leveraged the ubiquitin-proteasome system (UPS) to induce selective degradation of proteins by E3 ubiquitin ligases, which has great potential as novel therapeutics for human diseases, including cancer and ...

Novel E3 ubiquitin ligases that regulate histone protein levels in the budding yeast Saccharomyces cerevisiae. [PDF]
Core histone proteins are essential for packaging the genomic DNA into chromatin in all eukaryotes. Since multiple genes encode these histone proteins, there is potential for generating more histones than what is required for chromatin assembly.

The regulatory roles of the E3 ubiquitin ligase NEDD4 family in DNA damage response
E3 ubiquitin ligases, an important part of ubiquitin proteasome system, catalyze the covalent binding of ubiquitin to target substrates, which plays a role in protein ubiquitination and regulates different biological process. DNA damage response (DDR) is

Direct comparison of nick-joining activity of the nucleic acid ligases from bacteriophage T4 [PDF]
The genome of bacteriophage T4 encodes three polynucleotide ligases, which seal the backbone of nucleic acids during infection of host bacteria. The T4Dnl (T4 DNA ligase) and two RNA ligases [T4Rnl1 (T4 RNA ligase 1) and T4Rnl2] join a diverse array of ...

Identification of a novel motif in DNA ligases exemplified by DNA ligase IV [PDF]
DNA ligase IV is an essential protein that functions in DNA non-homologous end-joining, the major mechanism that rejoins DNA double-strand breaks in mammalian cells. LIG4 syndrome represents a human disorder caused by mutations in DNA ligase IV that lead to impaired but not ablated activity.

Analysis of ligation and DNA binding by Escherichia coli DNA ligase (LigA). [PDF]
NAD+-dependent DNA ligases are essential enzymes in bacteria, with the most widely studied of this class of enzymes being LigA from Escherichia coli. NAD+-dependent DNA ligases comprise several discrete structural domains, including a BRCT domain at the ...

Evaluation of NAD(+)-dependent DNA ligase of mycobacteria as a potential target for antibiotics [PDF]
Mycobacteria contain genes for several DNA ligases, including ligA, which encodes a NAD+-dependent enzyme that has been postulated to be a target for novel antibacterial compounds.

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 ...

The ubiquitin E3/E4 ligase, UBE4A, fine-tunes protein ubiquitylation and accumulation at sites of DNA damage facilitating double-strand break repair [PDF]
Double-strand breaks (DSBs) are critical DNA lesions that robustly activate the elaborate DNA damage response (DDR) network. We identified a critical player in DDR fine-tuning - the E3/E4 ubiquitin ligase, UBE4A.
