Insights

Researchers predicted the 3D structure of Cdh1, a protein involved in cancer, and designed potential inhibitory compounds. This structural insight could lead to new cancer treatments targeting Cdh1.

Area of Science:

  • Biochemistry
  • Structural Biology
  • Computational Chemistry

Background:

  • The anaphase-promoting complex (APC) regulates cell cycle and chromosome segregation.
  • APC activation depends on co-activators Cdh1 and Cdc20.
  • Cdh1 is implicated in cancer pathogenesis and represents a potential therapeutic target.

Purpose of the Study:

  • To predict the 3D structure of Cdh1.
  • To design novel inhibitory compounds targeting Cdh1 based on its predicted structure.

Main Methods:

  • Homology modeling using MODELLER.
  • Molecular dynamics simulations using the Gromacs package.
  • Virtual screening and molecular docking using AutoDock.

Main Results:

  • The 3D structure of Cdh1 was successfully predicted.
  • Cdh1 exhibits a propeller-like structure with DW40 repeats.
  • The binding pocket for inhibitory compounds was identified.

Conclusions:

  • The predicted Cdh1 structure provides a basis for rational drug design.
  • Identified binding pockets can guide the development of Cdh1 inhibitors.
  • This study offers potential strategies for developing new cancer therapeutics.

Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

Anaphase Promoting Complex00:50

Anaphase Promoting Complex

The stepwise destruction of specific proteins is necessary for the progression and completion of the cell cycle. Such proteins are ubiquitinated by ubiquitin ligases and then subsequently destroyed by the proteasome. The SCF (Skp1/Cullin/F-box) and the anaphase-promoting complex (APC) are two important ubiquitin ligases involved in cell cycle progression. While SCF is active throughout the cell cycle, APC gets activated during metaphase to anaphase transition. Cdc20 or Cdh1 binds to APC and...

Separation of Sister Chromatids02:17

Separation of Sister Chromatids

At the transition from prophase to metaphase, there is a reduction in cohesion along the chromosomal arms, resulting in the resolution of sister chromatids. However, residual cohesin connections remain to hold the sister chromatids together until the transition from metaphase to anaphase. The residual connection prevents any premature separation of sister chromatids, blocking the risks of aneuploidy within the daughter cells.
At the onset of anaphase, separase, a proteolytic enzyme, is...
