FAAP20
Domain
The UBZ2-type zinc finger binds both 'Lys-48'- and 'Lys-63'-linked polyubiquitin with preference for 'Lys-63'-linked polyubiquitin.
Function
Component of the Fanconi anemia (FA) complex required to recruit the FA complex to DNA interstrand cross-links (ICLs) and promote ICLs repair. Following DNA damage recognizes and binds 'Lys-63'-linked ubiquitin generated by RNF8 at ICLs and recruits other components of the FA complex. Promotes translesion synthesis via interaction with REV1.
Cellular localization
- Nucleus
- Chromosome
- Following DNA damage, recruited to DNA interstrand cross-links (ICLs) sites by binding to ubiquitin generated by RNF8.
