Dysregulation of ubiquitin ligases in cancer

Abstract: Ubiquitin ligases are critical components of the ubiquitin proteasome system (UPS), which governs fundamental processes regulating normal cellular homeostasis, metabolism, and cell cycle in response to external stress signals and DNA damage. Among multiple steps of the UPS system required to regulate protein ubiquitination and stability, UBLs define specificity, as they recognize and interact with substrates in a temporally- and spatially-regulated manner. Such interactions are required for substrate modificat… Show more

“…This process mediate cellular processes such as protein localization, cell cycle regulation and DNA damage repair [31]. Ubiquitin dys-regulation can affect tumour suppressor or oncogene leading to cellular transformation and cancer [32]. DNAJB1 binds to mitogen-inducible gene MIG6, a tumour suppressor, which positively regulates epidermal growth factor signalling, leading to breast cancer development [33].…”

“…The activity of many E3s is deregulated in cancer (Supplementary information S1 (table)) by epigenetic and genetic mechanisms and/or as a consequence of altered post-translational mechanisms, which are modified in response to extrinsic and intrinsic cues (reviewed in REF. 11) (FIG. 1).…”
