Fanconi anemia group L protein (FANCL) is an ubiquitin ligase that mediates ubiquitination of FANCD2, a key step in the DNA damage pathway. FANCL is required for proper primordial germ cell proliferation in the embryonic stage. Defects in FANCA are the cause of Fanconi anemia, a syndrome characterized by pancytopenia, congenital malformations and predisposition to cancers caused by a hypersensitivity to DNA-damaging agents, chromosomal instability and defective DNA repair.The synthetic peptide used to raise the antibody Cat. No. 200162 is selected from a sequence within the N-term region of human FANCL. For blocking experiments, a 10 to 100 fold molar excess to antibody is recommended.
