Cyclic nucleotide phosphodiesterases (PDEs) are diverse enzymes with multiple isozymes in mammals. This review details PDE nomenclature, structure, function, and their role in Trypanosmatidae parasite cell processes.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Parasitology

Context:

  • Recent advancements have significantly expanded the understanding of cyclic nucleotide phosphodiesterases (PDEs).
  • The existence of multiple, distinct isozymes across various mammalian tissues is now well-established.
  • Seven diverse PDE gene families have been identified, each with unique splice variants.

Purpose:

  • To provide a comprehensive overview of the current nomenclature, structure, and function of mammalian phosphodiesterase families.
  • To discuss the presence and functional significance of PDEs in cell proliferation and differentiation within Trypanosmatidae parasites.

Summary:

  • Mammalian cyclic nucleotide phosphodiesterases (PDEs) comprise seven gene families with numerous splice variants, each exhibiting distinct tissue expression and functions.
