Application: Anti-LIG4 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org). Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.
Biochem Physiol Actions: LIG4 (ligase IV) gene encodes a DNA ligase that links single-strand breaks in a double-stranded polydeoxynucleotide. The reaction is ATP-dependent. It is involved in the ligation step during non-homologous DNA end joining (NHEJ) and V(D)J recombination. NHEJ pathway repairs double-strand DNA breaks while V(D)J recombination involves the breakage and rejoining (dependent on NHEJ) of double-strand DNA.The protein forms a complex with the X-ray repair cross complementing protein 4 (XRCC4), which improves the joining activity of LIG4. This complex interacts with DNA-dependent protein kinase complex DNA-PK. This interaction is required for NHEJ. Defects in this gene cause LIG4 syndrome, characterized by immunodeficiency and developmental and growth delay.
