Cell division cycle-associated 7-like protein (CDCA7L/JPO2/R1) is closely related to CDCA7/JPO1; and like CDCA7, it plays a role in transcriptional regulation and interacts with c-Myc []. JPO2 overexpression induces metastasis in medulloblastoma []. JPO2 can interact directly and dynamically with chromatin, the dynamics of JPO2 chromatin binding being decelerated upon interaction with LEDGF/p75, which binds and tethers JPO2 to chromatin [, ].JPO2 inhibits monoamine oxidase A (MAOA) activity and gene expression by binding to the promoter []. JPO2 and MAOA act upstream of cyclin D1 and E2F1, and are involved in apoptotic signalling pathways [].
