RBM5 and neoplasm: Our group and others have successfully identified novel apoptotic controlling genes including LUCA15/RBM5 a novel tumor suppressor gene (Sutherland et al., 2000), fau (Finkel–Biskis–Reilly murine sarcoma virus (FBR-MuSV) associated ubiquitously expressed gene) (Mourtada-Maarabouni et al., 2003), vATPase (Anderson and Williams, 2003), protein phosphatase 4 (PP4) (Mourtada-Maarabouni et al., 2003), Toso (Hitoshi et al., 1998) and RACK-1 (Mourtada-Maarabouni et al., 2005).
