Replication in Eukaryotes

15.9K
In eukaryotic cells, DNA replication is highly conserved and tightly regulated. Multiple linear chromosomes must be duplicated with high fidelity before cell division, so there are many proteins that fulfill specialized roles in the replication process. Replication occurs in three phases: initiation, elongation, and termination, and ends with two complete sets of chromosomes in the nucleus.

DNA Distortion and Damage
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...

DNA Damage can Stall the Cell Cycle

9.7K
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...

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Genetics

Background:

  • Ubiquitin and ubiquitin-like proteins (UBLs) are crucial post-translational modifiers for maintaining genome stability.
  • Ubiquitin/UBL-conjugating enzymes (E2s) transfer ubiquitin/UBLs to substrate proteins as part of a larger enzymatic cascade.
  • E2s regulate chain topology, substrate specificity, and physiological outcomes impacting genome stability.

Purpose of the Study:

  • To review the role of E2s in maintaining genome stability.
  • To explore the potential of E2s as pharmacological targets for novel anti-cancer therapies.

Main Methods:

  • Literature review of current research on E2s and genome stability.
  • Analysis of structural and mechanistic studies on E2 function.
  • Evaluation of E2s as drug targets in cancer therapy.

Main Results:

  • E2s play a significant role in orchestrating ubiquitin/UBL substrate attachment.
  • E2s control critical aspects of protein modification that maintain genome stability.
  • Existing drug discovery efforts have overlooked E2s as potential targets.

Conclusions:

  • E2s are vital regulators of genome stability through their control of protein ubiquitination.
  • E2s represent a promising, yet underexplored, class of targets for developing innovative anti-cancer treatments.
