FunctionDNA repair protein that may operate in a postreplication repair or a cell cycle checkpoint function. May be implicated in interstrand DNA cross-link repair and in the maintenance of normal chromosome stability. Candidate tumor suppressor gene.
Tissue specificityHighly expressed in testis and thymus. Found in lymphoblasts.
Involvement in diseaseDefects in FANCG are a cause of Fanconi anemia (FA) [MIM:227650]. FA is a genetically heterogeneous, autosomal recessive disorder characterized by progressive pancytopenia, a diverse assortment of congenital malformations, 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.
Sequence similaritiesContains 4 TPR repeats.
Cellular localizationNucleus. Cytoplasm. The major form is nuclear. The minor form is cytoplasmic.
