MYBL2 overexpression on frequently amplified chromosome 20q promotes melanoma progression and poor survival, while its transactivation function is dispensable.
- Why it matters: Non-mutational drivers like transcription factor dysregulation are key in melanoma, but how MYBL2 drives oncogenic programs without canonical activity is unclear.
- What they did: The study mapped a non-canonical RNA-binding role for MYBL2 using melanoma-associated RNA interactions, then tested a decoy RNA that disrupts MYBL2–RNA binding.
- The result: MYBL2–RNA interactions shift chromatin toward an AP-1-permissive state and increase MAFG and FRA1 chromatin association; the decoy RNA impaired these interactions and suppressed melanoma cell growth.
