For example, the 113-aa protein (p113) encoded by hsa_circ_30402 interacts with Zuotin-related factor 1 (ZRF1) and bromodomain protein 4 (BRD4) to form a transcriptional regulatory complex inducing lipid metabolic repro-gramming and mitochondrial complex I activity, which enhances the oncogenic effects of neuroblastoma cells [18]. The gene discussed is DNAJC2; the disease is neuroblastoma.
