Abstract:
F-box proteins, which are the substrate-recognition subunits of SKP1-cullin 1-F-box protein (SCF) E3 ligase complexes, have pivotal roles in multiple cellular processes through ubiquitylation and subsequent degradation of target proteins. Dysregulation of F-box protein-mediated proteolysis leads to human malignancies. Notably, inhibitors that target F-box proteins have shown promising therapeutic potential, urging us to review the current understanding of how F-box proteins contribute to tumorigenesis. As the physiological functions for many of the 69 putative F-box proteins remain elusive, additional genetic and mechanistic studies will help to define the role of each F-box protein in tumorigenesis, thereby paving the road for the rational design of F-box protein-targeted anticancer therapies.
Insights
F-box proteins regulate cell processes via ubiquitylation. Their dysregulation drives cancer, but targeting them offers therapeutic promise for future anticancer treatments.
Area of Science:
- Molecular Biology
- Cellular Biology
- Biochemistry
Background:
- F-box proteins are key components of SKP1-cullin 1-F-box protein (SCF) E3 ligase complexes.
- These complexes mediate protein ubiquitylation and degradation, crucial for cellular processes.
- Dysregulation of F-box protein activity is linked to human cancer development.
Purpose of the Study:
- To review the current understanding of F-box proteins in tumorigenesis.

Cancer-Critical Genes I: Proto-oncogenes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
