Fig. 4: Perifosine regulates RAD51 ubiquitination by inhibiting UCHL3.

a Control and UCHL3 knockout MDA-MB-231 cells were treated with perifosine and lysates were used for immunoprecipitation and western blot as indicated. b Examination of Rad51 ubiquitination in cells treated with perifosine. c In vitro deubiquitination analysis of UCHL3 in the presence or absence of perifosine
