Nucleus-translocated CaMKII isoforms have shown previously and in the present study to regulate cell cycle in irradiated K562 CML [(Heise et al., 2010) and present study], Jurkat T cell leukemia (Klumpp et al., 2016), and glioblastoma cells (Klumpp et al., 2017). The gene discussed is CAMK2G; the disease is glioblastoma.
