Summary

Aberrant intracellular calcium (Ca2+) homeostasis, regulated by Ca2+-binding proteins, is linked to neurodegenerative disorders. This chapter examines S100B and S100A6 proteins in the central nervous system and their diagnostic potential.

Area of Science:

  • Neuroscience
  • Molecular Biology
  • Biochemistry

Background:

  • Neurodegenerative disorders are often linked to disruptions in intracellular calcium (Ca2+) homeostasis.
  • Ca2+-binding proteins play a critical role in regulating cellular Ca2+ levels.

Purpose of the Study:

  • To focus on S100B and S100A6 proteins, which are highly expressed in the central nervous system.
  • To discuss the protein structures, cellular localizations, and association with brain pathology.
  • To explore the potential of these proteins in clinical diagnostics.

Main Methods:

  • Literature review and synthesis of existing research on S100B and S100A6 proteins.
  • Analysis of protein structure and localization data.
  • Examination of studies linking these proteins to neurodegenerative conditions.

Main Results:

  • S100B and S100A6 are key Ca2+-binding proteins abundant in the central nervous system.
  • Alterations in their structure, localization, or expression are associated with various brain pathologies.
  • These proteins show promise as biomarkers for neurodegenerative diseases.

Conclusions:

  • S100B and S100A6 are implicated in the pathogenesis of neurodegenerative disorders due to their role in Ca2+ homeostasis.
  • Understanding their function and pathology is crucial for developing diagnostic tools.
  • Further research into S100B and S100A6 could lead to novel clinical applications for diagnosing and potentially treating brain diseases.
