Next, we generated three deletion mutants of OTUD7B: OTUD7BΔZnF (Zinc Finger domain deleted, aa 1-1077), OTUD7BΔOTU (Ovarian Tumor domain deleted, aa 1-564 & 1078-2532), and OTUD7BNt (UBA domain-containing, 1-564) using the SFB-OTUD7B plasmid (Figure 2C) and attempted to identify the LEF1-binding region on OTUD7B. The gene discussed is OTUD7B; the disease is ovarian neoplasm.
