Disease
[FANCL_HUMAN] Fanconi anemia. The disease is caused by mutations affecting the gene represented in this entry.
Function
[FANCL_HUMAN] Ubiquitin ligase protein that mediates monoubiquitination of FANCD2, a key step in the DNA damage pathway. Also mediates monoubiquitination of FANCI. May stimulate the ubiquitin release from UBE2W. May be required for proper primordial germ cell proliferation in the embryonic stage, whereas it is probably not needed for spermatogonial proliferation after birth.[1] [2] [3] [4] [5]
Publication Abstract from PubMed
The Fanconi Anemia (FA) pathway is essential for the repair of DNA interstrand cross-links. At the heart of this pathway is the monoubiquitination of the FANCI/FANCD2 (ID) complex by the multiprotein 'core complex' containing the E3 ubiquitin ligase FANCL. Vertebrate organisms have the 8-protein core complex, while invertebrates apparently do not. We report here the structure of the central domain of human FANCL in comparison with the recently solved Drosophila melanogaster FANCL. Our data represent the first structural detail into the catalytic core of the human system, and reveal that the central fold of FANCL is conserved between species. However, there are macromolecular differences between the FANCL proteins that may account for the apparent distinctions in core complex requirements between the vertebrate and invertebrate FA pathways. In addition we characterize the binding of human FANCL with its partners, Ube2t, FANCD2 and FANCI. Mutational analysis reveals, which residues are required for substrate binding, and we also show the domain required for E2 binding.
