ATP-dependent DNA ligases.

Genome biology, 2002
By catalyzing the joining of breaks in the phosphodiester backbone of duplex DNA, DNA ligases play a vital role in the diverse processes of DNA replication, recombination and repair. Three related classes of ATP-dependent DNA ligase are readily apparent in eukaryotic cells.

Silencing Myostatin Using In Vivo Self‐Assembled siRNA Protects Against Cancer‐ and Dexamethasone‐Induced Muscle Atrophy

Advanced Healthcare Materials, EarlyView.
This study reports an in vivo self‐assembled siRNA strategy that enables the liver to generate small extracellular vesicles (sEVs) tagged with a muscle‐targeting peptide (MSP) and naturally loaded with myostatin (MSTN)‐siRNA. These MSP‐tagged sEVs are systemically delivered to skeletal muscle, efficiently silence MSTN, promote muscle hypertrophy, and ...

Case Report: Hypomorphic Ligase 4 deficiency – a paradigm of immunodysregulation

Frontiers in Immunology
DNA Ligase 4 is critical to nonhomologous end joining, necessary for V(D)J recombination in T and B cell development. Ligase 4 deficiency is a rare autosomal recessive disorder caused by hypomorphic mutations in the DNA Ligase 4 gene, that can lead to a ...

Evolution of DNA ligases of Nucleo-Cytoplasmic Large DNA viruses of eukaryotes: a case of hidden complexity

Biology Direct, 2009
Background Eukaryotic Nucleo-Cytoplasmic Large DNA Viruses (NCLDV) encode most if not all of the enzymes involved in their DNA replication. It has been inferred that genes for these enzymes were already present in the last common ancestor of the NCLDV ...

DNA ligases as therapeutic targets.

Translational cancer research, 2013
During DNA replication, DNA joining events link Okazaki fragments on the lagging strand. In addition, they are required to repair DNA single- and double-strand breaks and to complete repair events initiated by the excision of mismatched and damaged bases. In human cells, there are three genes encoding DNA ligases.
