This SpringerBrief explores the physiological roles of Skp1-Cullin1-F-box Complex (SCF) and Anaphase Promoting Complex (APC) in normal cells and in tumor formation. These two related, multi-subunit E3 ubiquitin ligase enzymes, APC and SCF are thought to be the major driving forces governing proper cell cycle progression. Defective cell cycle regulation leads to genomic instability and ultimately, cancer development. Selective degradation of key cell cycle regulators by the ubiquitin-proteasome system has been proven to be a major regulatory mechanism for ensuring ordered and coordinated cell cycle progression. The SCF and APC E3 ligases have been characterized to play pivotal roles in regulating the cell cycle progression by timely degrading various critical cell cycle regulators. This Brief reviews recent studies that have shown that deregulation of signaling pathways in which the two ubiquitin ligases are involved causes aberrant cell cycle regulation, in turn leading to tumorigenesis. The text also discusses how SCF and APC may present promising therapeutic targets to treat various cancers.

This book summarizes all the important aspects of CRLs (Cullin-RING E3 Ubiquitin Ligases), while providing details of mechanistic specifics that go beyond protein ubiquitination and neddylation. Ubiquitin ligases, including the CRLs, which are activated by neddylation, play an important role in diverse biological processes and are involved in various human diseases, particularly cancer. The book covers various topics, such as CRL structure, biology, genetics, its regulation by neddylation, its pivotal role in human disease, and its potential in drug discovery and targeted therapies. The book appeals to biochemists and biologists working in other fields, and, given the importance of CRLs in all aspects of cell biology and the great promise of targeting these complexes for therapy, is a valuable resource anyone interested in modern biology or medicine.
