Abstract:
Cullin-5 (CUL5), a scaffold protein in active cullin-RING ubiquitin ligase (CRL) complexes, is a member of the cullin family of proteins. The CUL5-type ubiquitin ligase can target multiple proteins involved in ubiquitination and proteasome degradation. CUL5 plays positive roles in regulating cell growth, proliferation and physiological and other processes in the human body. It has been found that the expression of CUL5 is significantly downregulated in various cancer cells, which affects the course of the cancers. Here, we reviewed the current data on the expression and role of CUL5 in both normal and cancer cells, its possible mechanisms, and its potential as a therapeutic target for cancers.
Insights

M-Cdk Drives Transition Into Mitosis
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.

Loss of Tumor Suppressor Gene Functions
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
