Histone acetylation modifies gene transcription and chromatin dynamics. This review explores histone acetyltransferase complexes, their partner proteins, and functions beyond catalysis.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Epigenetics

Background:

  • Histone acetylation is crucial for gene transcription and chromatin dynamics.
  • Numerous histone acetyltransferases (HATs) have been identified recently.
  • Many HATs function as transcriptional regulators and exist in larger protein complexes.

Purpose of the Study:

  • To review the association of HATs with partner proteins.
  • To discuss the functional attributes of HAT complexes beyond their catalytic activity.

Main Methods:

  • Literature review of recent reports on HAT purification and identification.
  • Analysis of protein-protein interactions within HAT complexes.
  • Functional characterization of HAT complexes.

Related Experiment Videos

Main Results:

  • HATs frequently associate with various partner proteins.
  • These complexes possess functions beyond simple acetylation.
  • Understanding these complexes provides deeper insights into gene regulation.

Conclusions:

  • HAT complexes are integral to gene expression regulation.
  • The functional diversity of HAT complexes is extensive.
  • Further research into HAT complexes will illuminate chromatin dynamics and transcriptional control.
