Regulator of deubiquitinating complexes, which acts as a strong activator of usp1, usp12 and usp46. Enhances the usp1-mediated deubiquitination of fancd2; usp1 being almost inactive by itself. Activates deubiquitination by increasing the catalytic turnover without increasing the affinity of deubiquitinating enzymes for the substrate. Also activates deubiquitinating activity of complexes containing usp12. Together with rad51ap1, promotes DNA repair by stimulating rad51-mediated homologous recombination. Binds single-stranded DNA (ssDNA) and double-stranded DNA (dsDNA). DNA-binding is required both for usp1-mediated deubiquitination of fancd2 and stimulation of rad51-mediated homologous recombination: both wdr48/uaf1 and rad51ap1 have coordinated role in DNA-binding during these processes.
