Fanconi anemia (FA) is a rare autosomal recessive disorder characterized clinically by congenital abnormalities, progressive bone marrow failure and cancer susceptibility. Cells from individuals with Fanconi anemia manifest features of spontaneous chromosomal instability and hypersensitivity to DNA cross-linking agents such as mitomycin C. Over 11 known Fanconi anemia gene products are involved in DNA damage response pathway. In the pathway, monoubiquitination of FANCD2 is a key step. A novel protein FANCL is a component of the nuclear FA complex, functioned as an ubiquitin E3 ligase and monoubiquitinylated FANCD2. FANCD2-Ub is targeted to chromatin, where it interacts with BRCA2 to repair DNA damage. In early embryo stage, FA pathway is probably involved in proliferation of PGCs. Mice deficient in FA proteins, such as FANCL, FANCC and FANCA, have a drastic reduction of primordial germ cells (PGC), resulting in male and female infertility in adult. In the adult male, FANCL and a few testis-specific proteins, GGN1 (gametogenetin protein 1), GGNBP1 (gametogenetin binding protein 1), GGNBP2 and OAZ3 (ornithine decarboxylase antizyme 3) form a novel testis-specific complex functioning in spermatogenesis. FANCL is involved in proliferation of PGCs in early embryo stage, and development of germ cells in adult.
