The genetic connections between DNA repair pathways and human cancer predisposition have fueled interest in the proteins that recognize and repair specific sites of DNA damage. The repair enzymes are ...

However, current methods like DNA ligase-linked hydrogels present many challenges, including potential allergic reactions and complex administration procedures that limit clinical applications.

Causes: LIG4 syndrome is caused by a mutation in the LIG4 gene, which carries the instructions needed to make a protein known as DNA ligase 4. This protein is an enzyme that helps repair a ...

ATP-dependent RNA ligases join 3’-OH and 5’-PO 4 RNA termini via three nucleotidyl transfer steps similar to those of DNA ligases: (Step 1) ligase reacts with ATP to form a covalent ...

Disappearance of SUMO-modified Mdm2, which is observed upon radiation, may thus be a prerequisite for DNA-damage-induced ... makes Mdm2 a better or worse ligase remains a puzzle to be solved.
