Fanconi recognition complex as FA core complex recruits NER, HR, TLS proteins that collectively repair the ICL. If Fanconi proteins participating in the recognition are dysactivated, there is no any other mechanism to recognize ILSs, therefore, even if NER, HR and TLS are correct, they will not perform the repair without core Fanconi proteins.
