Target intelligence / Profile preview

Fanconi anemia complementation group F protein (FANCF)

Target: FANCF
Molecular classification: DNA repair protein, Adapter protein (within FA nuclear core complex)

Overview

FANCF is a DNA repair protein that acts as a molecular adaptor in the Fanconi anemia nuclear core complex, bridging key subcomplexes (A:G and C:E) and facilitating the monoubiquitination of FANCD2, an essential step in interstrand DNA crosslink repair. Mutations or deficiencies in FANCF protein lead to Fanconi anemia, characterized by chromosomal instability, hypersensitivity to DNA damaging agents, and increased cancer risk. FANCF enables proper assembly of the FA core complex and normal cellular response to DNA-crosslinking chemotherapy agents such as mitomycin C.

Other names: FA complementation group FFAF

Mechanism of action

Drugs targeting FANCF aim to restore or exploit DNA repair deficiencies, sensitize cancer cells to DNA cross-linking agents, or monitor activity during genotoxic treatments

Biological functions

DNA repair (interstrand crosslink repair)Cellular resistance to DNA cross-linking agentsMaintenance of chromosomal stability

Disease associations

Cancer (especially via genome instability)Fanconi anemia (hereditary DNA repair disorder)

Safety considerations

Targeting FANCF or disrupting its function could lead to increased chromosomal instability and heightened sensitivity to DNA-damaging agents, increasing cancer or bone marrow failure risk

Interacting drugs

Mitomycin C

Biomarkers

FANCF methylation or expression status
