NSUN2 and leukemia: A number of proteins were identified that have not previously been associated with RAR complexes, including the AR, alongside other proteins that impact AR function including NSUN2 which is required for translation of AR mRNA (74) as well as SART3, which is a splicing factor and regulates AR-dependent transcription(75) and has also been identified in leukemia as part of a fusion gene with RARG (SART3:RARG)(76).
