Overview of Gene Research
Faap20, also known as 20-kDa FANCA-associated protein, is an integral component of the Fanconi anemia (FA) core complex. It plays essential roles in DNA repair pathways, especially in homology-directed repair of DNA double-strand breaks, which is crucial for maintaining genome integrity [1]. The FA pathway, in which Faap20 is involved, is a multi-step DNA repair process at stalled replication forks in response to DNA interstrand cross-links (ICLs) [2].
Deletion of Faap20 in mice led to a mild FA-like phenotype with defects in the reproductive and hematopoietic systems. Faap20 -/- mice are susceptible to mitomycin C (MMC)-induced pancytopenia. Faap20 -/- hematopoietic stem and progenitor cells (HSPCs) showed defects in long-term multilineage reconstitution and aberrant cell cycle patterns during chronic MMC treatment [4].
In conclusion, Faap20 is vital for DNA repair and genome maintenance, as demonstrated by the phenotypes in Faap20 knockout mouse models. These models help us understand the role of Faap20 in the context of diseases related to FA, such as hematologic defects and cancer predisposition [3,4].
