Insights

DNA damage response relies on protein kinases and phosphatases. This review highlights new roles for phosphatases in maintaining genomic stability and their potential as cancer therapy targets.

Area of Science:

  • Molecular Biology
  • Cellular Biology
  • Biochemistry

Background:

  • The cellular response to DNA damage is vital for genomic integrity and cancer prevention.
  • Serine/threonine (Ser/Thr) protein kinases are key activators of this response.
  • Emerging evidence indicates Ser/Thr phosphatases critically modulate these kinases and their substrates.

Purpose of the Study:

  • To review recent findings on the novel functions and regulation of Ser/Thr phosphatases.
  • To explore the involvement of phosphatases in cancer progression.
  • To identify phosphatases as potential therapeutic targets in cancer treatment.

Main Methods:

  • Literature review of recent scientific reports.
  • Analysis of studies on phosphatase function and regulation.
  • Synthesis of information regarding phosphatase involvement in cancer pathways.

Main Results:

  • Phosphatases, like kinases, are integral to the DNA damage response pathway.
  • New regulatory mechanisms and functions of phosphatases have been identified.
  • Phosphatases play a significant role in cancer development and progression.

Conclusions:

  • Ser/Thr phosphatases are crucial regulators of the DNA damage response.
  • Dysregulation of phosphatases contributes to cancer progression.
  • Targeting phosphatases offers a promising strategy for novel cancer therapies.

Phosphorylation01:02

Phosphorylation

The addition or removal of phosphate groups from proteins is the most common chemical modification that regulates cellular processes. These modifications can affect the structure, activity, stability, and localization of proteins within cells as well as their interactions with other proteins.
During phosphorylation, protein kinases transfer the terminal phosphate group of ATP to specific amino acid side chains of substrate proteins. Serine, threonine, and tyrosine are the most commonly...

DNA Damage Can Stall the Cell Cycle

In response to DNA damage, cells can pause the cell cycle to assess and repair the breaks. However, the cell must check the DNA at certain critical stages during the cell cycle. If the cell cycle pauses before DNA replication, the cells will contain twice the amount of DNA. On the other hand, if cells arrest after DNA replication but before mitosis, they will contain four times the normal amount of DNA. With a host of specialized proteins at their disposal,cells must use the right protein at...

Protein Kinases and Phosphatases02:54

Protein Kinases and Phosphatases

Proteins undergo chemical modifications that trigger changes in the charge, structure, and conformation of the proteins. Phosphorylation, acetylation, glycosylation, nitrosylation, ubiquitination, lipidation, methylation, and proteolysis are various protein modifications that regulate protein activity. Such modifications are usually enzyme-driven.
Protein kinases
Many proteins in the cell are regulated by phosphorylation, the addition of a phosphate group. A family of enzymes called kinases...
Base Excision Repair01:54

Base Excision Repair

One of the common DNA damages is the chemical alteration of single bases by alkylation, oxidation, or deamination. The altered bases cause mispairing and strand breakage during replication. This type of damage causes minimal change to the DNA double helix structure and can be repaired by the base excision repair (BER) pathways. BER corrects damaged DNA sequences by removing the damaged base and restoring the original base sequence using the complementary strand as a template.
The first step of...

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:
