The intracellular distribution of TRAF3IP2-AS1 suggested that TRAF3IP2-AS1 might also have a post-transcriptional regulation function that contributes to NONO-TFE3 tRCC progression. The gene discussed is TRAF3IP2; the disease is renal cell carcinoma associated with Xp11.2 translocations/TFE3 gene fusions.
