Recombinant human FANCB protein is a key reagent in studying Fanconi anemia (FA), a rare genetic disorder characterized by genomic instability, bone marrow failure, and cancer predisposition. FANCB, located on the X chromosome, is part of the FA core complex, a multi-protein assembly essential for DNA interstrand crosslink (ICL) repair. This complex monoubiquitinates FANCI-FANCD2 heterodimers, initiating downstream repair via homologous recombination. Mutations in FANCB disrupt this pathway, leading to defective DNA repair and FA pathogenesis.
Recombinant FANCB is typically produced using mammalian expression systems to ensure proper post-translational modifications. Its purification involves affinity chromatography and quality assessments (e.g., SDS-PAGE, Western blot) to validate structural integrity. Researchers employ this protein to dissect molecular mechanisms of FA, model disease-associated mutations, and screen potential therapeutics.
Notably, recombinant FANCB holds therapeutic potential, particularly for X-linked FA cases. Its use in gene therapy or protein replacement strategies could restore DNA repair function in patient-derived cells. Additionally, it serves as a critical tool for elucidating crosstalk between FA pathways and other DNA damage response networks, aiding the development of targeted cancer treatments. As FA research advances, recombinant FANCB remains vital for both basic science and translational applications.
