  • Function

    Required for maintenance of chromosomal stability. Involved in the repair of DNA double-strand breaks by homologous recombination and in the repair of DNA cross-links. Participates in S phase and G2 phase checkpoint activation upon DNA damage. Promotes FANCD2 ubiquitination and recruitment to DNA repair sites.
  • Involvement in disease

    Defects in FANCI are a cause of Fanconi anemia complementation group I (FANCI) [MIM:609053]. It is a disorder affecting all bone marrow elements and resulting in anemia, leukopenia and thrombopenia. It is associated with cardiac, renal and limb malformations, dermal pigmentary changes, and a predisposition to the development of malignancies. At the cellular level it is associated with hypersensitivity to DNA-damaging agents, chromosomal instability (increased chromosome breakage) and defective DNA repair.
  • Domain

    The C-terminal 30 residues are probably required for function in DNA repair.
  • Post-translational

    Monoubiquitinated on Lys-523 during S phase and upon genotoxic stress. Deubiquitinated by USP1 as cells enter G2/M, or once DNA repair is completed. Monoubiquitination requires the FANCA-FANCB-FANCC-FANCE-FANCF-FANCG-FANCM complex. Ubiquitination is required for binding to chromatin, DNA repair, and normal cell cycle progression.
    Phosphorylated in response to DNA damage by ATM and/or ATR.
  • Cellular localization

    Nucleus. Concentrates in nuclear foci upon genotoxic stress.

  • All lanes : Anti-FANCI (phospho S556) antibody (ab228516) at 1/1000 dilution

    Lane 1 : HeLa (human epithelial cell line from cervix adenocarcinoma) cell lysate
    Lane 2 : HeLa (human epithelial cell line from cervix adenocarcinoma) cell lysate treated with lambda phosphatase (800 units/1mg protein for 30 min)

    Predicted band size: 149 kDa

    Phosphospecificity is shown in Lane 2 where immunolabeling is completely eliminated by lysate treatment with lambda phosphatase (800 units/1mg protein for 30 min).
