PML nuclear bodies.
PML nuclear bodies are matrix-associated domains that recruit an astonishing variety of seemingly unrelated proteins. Since their discovery in the early 1960s, PML bodies have fascinated cell biologists because of their beauty and their tight association with cellular disorders. The identification of PML, a gene involved in an oncogenic chromosomal translocation, as the key organizer of these d...

متن کاملIs PML a Tumor Suppressor?
The role of the promyelocytic leukemia (PML) protein has been widely tested in many different contexts, as attested by the hundreds of papers present in the literature. In most of these studies, PML is regarded as a tumor suppressor, a notion on the whole accepted by the scientific community. In this review, we examine how the concept of tumor-suppressor gene has evolved until now and then syst...
متن کاملViruses as hijackers of PML nuclear bodies.
Promyelocytic leukemia nuclear bodies (PML-NBs) are discrete interchromosomal macromolecular structures. The integrity of this dynamic nuclear subcompartment critically depends on the presence of the name-giving PML protein. Among the permanent or transient residents of PML-NBs are various regulatory proteins, including Sp100, CBP, pRb, HIPK2, RAD51 and p53. PML-NBs are frequently targeted by v...
متن کاملTwo-step colocalization of MORC3 with PML nuclear bodies.
Many functional subdomains, including promyelocytic leukemia nuclear bodies (PML NBs), are formed in the mammalian nucleus. Various proteins are constitutively or transiently accumulated in PML NBs in a PML-dependent manner. MORC3 (microrchidia family CW-type zinc-finger 3), also known as NXP2, which consists of GHL-ATPase, a CW-type zinc-finger and coiled-coil domains, is localized in PML NBs,...
