title: Protein ubiquitination in lymphoid malignancies.
abstract: Human lymphoid malignancies inherit gene expression networks from their normal B-cell counterpart and co-opt them for their own oncogenic purpose, which is usually governed by transcription factors and signaling pathways. These transcription factors and signaling pathways are precisely regulated at multiple steps, including ubiquitin modification. Protein ubiqutination plays a role in almost all cellular events and in many human diseases. In the past few years, multiple studies have expanded the role of ubiquitination in the genesis of diverse lymphoid malignancies. Here, we discuss our current understanding of both proteolytic and non-proteolytic functions of the protein ubiquitination system and describe how it is involved in the pathogenesis of human lymphoid cancers. Lymphoid-restricted ubiquitination mechanisms, including ubiquitin E3 ligases and deubiquitinating enzymes, provide great opportunities for the development of targeted therapies for lymphoid cancers.
