Stealing the spotlight: CUL4-DDB1 ubiquitin ligase docks WD40-repeat proteins to destroy
Cell Division, 2007 Recent investigation of Cullin 4 (CUL4) has ushered this class of multiprotein ubiquitin E3 ligases to center stage as critical regulators of diverse processes including cell cycle regulation, developmental patterning, DNA replication, DNA damage and ...

Saccharomyces cerevisiae DNA ligase IV supports imprecise end joining independently of its catalytic activity. [PDF]
PLoS Genetics, 2013 DNA ligase IV (Dnl4 in budding yeast) is a specialized ligase used in non-homologous end joining (NHEJ) of DNA double-strand breaks (DSBs). Although point and truncation mutations arise in the human ligase IV syndrome, the roles of Dnl4 in DSB repair ...

Spatial and temporal cellular responses to single-strand breaks in human cells [PDF]
, 2003 DNA single-strand breaks (SSB) are one of the most frequent DNA lesions produced by reactive oxygen species and during DNA metabolism, but the analysis of cellular responses to SSB remains difficult due to the lack of an experimental method to produce ...

The Action of DNA Ligase at Abasic Sites in DNA [PDF]
Journal of Biological Chemistry, 1998 Apurinic/apyrimidinic (AP) sites occur frequently in DNA as a result of spontaneous base loss or following removal of a damaged base by a DNA glycosylase. The action of many AP endonuclease enzymes at abasic sites in DNA leaves a 5'-deoxyribose phosphate (dRP) residue that must be removed during the base excision repair process.

Alternative Okazaki Fragment Ligation Pathway by DNA Ligase III
Genes, 2015 Higher eukaryotes have three types of DNA ligases: DNA ligase 1 (Lig1), DNA ligase 3 (Lig3) and DNA ligase 4 (Lig4). While Lig1 and Lig4 are present in all eukaryotes from yeast to human, Lig3 appears sporadically in evolution and is uniformly present ...

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

An improved protocol for small RNA library construction using High Definition adapters [PDF]
, 2015 Next generation sequencing of small RNA (sRNA) libraries is widely used for studying sRNAs in various biological systems. However, cDNA libraries of sRNAs are biased for molecules that are ligated to adapters more or less efficiently than other molecules.
