FANCL (FA complementation group L) encodes the catalytic E3 ubiquitin ligase subunit of the Fanconi anemia (FA) core complex. As the key catalytic component, FANCL is essential for monoubiquitinating FANCD2 and FANCI, the central activation steps in the FA DNA damage response pathway. Biallelic mutations in FANCL cause Fanconi Anemia type L, characterized by bone marrow failure, congenital abnormalities, and predisposition to cancer.
The FANCL gene is located on chromosome 2p16.3 and encodes a protein of 380 amino acids. It functions as the E3 ubiquitin ligase within the FA core complex, a multiprotein assembly essential for DNA interstrand crosslink (ICL) repair. The FA pathway is crucial for maintaining genomic stability, and defects in this pathway lead to Fanconi anemia, a rare autosomal recessive disorder characterized by progressive bone marrow failure, developmental abnormalities, and high cancer risk.
FANCL is the catalytic E3 ubiquitin ligase subunit of the Fanconi anemia (FA) core complex. It is responsible for the monoubiquitination of FANCD2 and FANCI, which is the key activation step in the FA DNA repair pathway.
Key functions include:
FANCL is expressed in most tissues:
The study of Fancl Gene has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
