The Ubiquitin-Conjugating Enzyme E2 O (UBE2O) and Its Therapeutic Potential in Human Leukemias and Solid Tumors

Simple Summary This review provides a comprehensive and detailed explanation of the various functions of the ubiquitin-conjugating enzyme E2 O (UBE2O). It examines UBE2O's role in a wide range of biological processes under both physiological and pathological conditions. The review also explores UBE2O's involvement in several human cancers, with a particular focus on its role in leukemias and solid cancers. Furthermore, this review delves into the dual role of UBE2O, not only as a potential therapeutic target but also as a crucial factor in the regulation of the development and progressoin of several human malignancies. In summary, this review underscores UBE2O importance in cancer biology and its potential for future therapeutic applications.Abstract Protein degradation is a biological phenomenon essential for cellular homeostasis and survival. Selective protein degradation is performed by the ubiquitination system which selectively targets proteins that need to be eliminated and leads them to proteasome degradation. In this narrative review, we focus on the ubiquitin-conjugating enzyme E2 O (UBE2O) and highlight the role of UBE2O in many biological and physiological processes. We further discuss UBE2O's implications in various human diseases, particularly in leukemias and solid cancers. Ultimately, our review aims to highlight the potential role of UBE2O as a therapeutic target and offers new perspectives for developing targeted treatments for human cancers.
