| HGNC Family | OTU domain containing (OTUD) |
| Name | OTU deubiquitinase 6A |
| Description | Deubiquitinating enzymes (DUBs; see MIM 603478) are proteases that specifically cleave ubiquitin (MIM 191339) linkages, negating the action of ubiquitin ligases. DUBA2 belongs to a DUB subfamily characterized by an ovarian tumor (OTU) domain.[supplied by OMIM, May 2008] |
| Summary |
{"type": "root", "children": [{"type": "p", "children": [{"type": "t", "text": "\nOTUD6A is an ovarian tumor-associated deubiquitinase that has emerged as a critical regulator of mitochondrial dynamics in cancer cells. In colorectal cancer, OTUD6A removes ubiquitin from the mitochondrial fission effector Drp1, increasing its protein stability and half-life, which in turn enhances mitochondrial fission. This modulation of mitochondrial morphology contributes to heightened cancer cell growth and tumorigenesis by promoting an environment that favors cell proliferation and survival."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": ""}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nIn addition to its role in mitochondrial dynamics, OTUD6A has been implicated in the oncogenic process of prostate cancer. Here, OTUD6A is found to be exclusively amplified and overexpressed, where it acts as a physiological deubiquitinase for the oncoprotein c-Myc. By deubiquitinating and stabilizing c-Myc, OTUD6A sustains its high levels, thereby driving metabolic remodeling and promoting prostatic tumorigenesis."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "2"}]}, {"type": "t", "text": ""}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nFurthermore, OTUD6A plays a pivotal role in the DNA damage response by targeting TopBP1, a key mediator of genomic integrity. Following DNA damage, OTUD6A is upregulated and dephosphorylated by PP2A, which facilitates its nuclear localization and recruitment to sites of damage. At these sites, OTUD6A binds TopBP1 and interferes with its ubiquitination by the E3 ligase UBR5, leading to increased stability of TopBP1. This stabilization is essential for proper CHK1 activation and cell cycle progression under replication stress, ultimately conferring resistance to chemoradiotherapy and contributing to tumor development."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "3"}]}, {"type": "t", "text": ""}]}, {"type": "rg", "children": [{"type": "r", "ref": 1, "children": [{"type": "t", "text": "Le Shi, Jing Liu, Yunhua Peng, et al.
