    CATEGORY regulatory
    SUBCELLULAR LOCALIZATION     intracellular
  • found in mitochondria
  • basic FUNCTION
  • putatively involved in DNA-post replication repair or cell cycle checkpoint control
  • may have a role in protection against oxidative DNA damage
  • protection of the genomic integrity of cells and maintenance of normal chromosome stability
  • required to prevent accumulation of replication-associated DNA double-strand breaks
  • Fanconi anemia proteins, including FANCG are functionally involved in several complex cellular pathways including transcription regulation, cell signaling, oxidative metabolism, and cellular transport
  • predicted to play a key role in the assembly and/or stabilization of the nuclear FA protein core complex
  • phosphorylation of serine 7 in FANCG is functionally important in the FA pathway
  • may have a role independent of the FA core complex
  • a critical role in neural stem and progenitor cells during developmental and adult neurogenesis
  • promotes formation of a newly identified protein complex containing BRCA2, FANCD2 and XRCC3

  • Fancg(-/-) mice have normal viability and no gross developmental abnormalities but their primary splenic lymphocytes, bone marrow progenitor cells, and fibroblasts display spontaneous chromosome breakage and increased sensitivity to mitomycin C and ionizing radiation. Fancg(-/-) mice have decreased fertility and abnormal gonadal histology
  • Fancg/Xrcc9 null mice show showed hypogonadism and impaired fertility and hypersensitivity to mitomycin C
  • fancg(-/-) mice presented with microcephalies and a decreased neuronal production in developing cortex and adult brain
