Simultaneously, lncRNA TERRA was reported to be enriched in ALT-associated PML body (APB), one of the promyelocytic leukemia (PML) bodies, which are nuclear membraneless organelles formed by LLPS and are involved in mitosis by recruiting multivalent proteins with small ubiquitin-like modification (SUMO) sites and SUMO-interacting motifs (SIMs) (Arora et al., 2014; Banani et al., 2016). Here, PML is linked to acute promyelocytic leukemia.
