Background:

  • Capacitative calcium entry (CCE) is a critical calcium influx pathway.
  • CCE is activated when intracellular calcium stores are depleted.
  • This pathway is essential for refilling these stores and maintaining cellular calcium homeostasis.

Purpose of the Study:

  • To review the current understanding of capacitative calcium entry.
  • To highlight the remaining challenges in elucidating CCE.
  • To identify key areas for future research in CCE.

Main Methods:

  • Literature review of recent studies on capacitative calcium entry.
  • Analysis of experimental data on calcium signaling and store-operated calcium channels.
  • Synthesis of findings to identify knowledge gaps.

Main Results:

  • CCE is a fundamental mechanism for calcium regulation.
  • Significant progress has been made in understanding CCE.
  • Key questions regarding CCE's molecular identity, biophysical properties, and the nature of the store depletion signal persist.

Conclusions:

  • Capacitative calcium entry is vital for cellular function.
  • Further research is required to fully understand the molecular and biophysical aspects of CCE.
  • Identifying the store depletion signal is crucial for advancing CCE research.
