Store-operated calcium entry (SOCE) regulates cellular calcium signaling. This review details SOCE regulatory mechanisms and proteins involved in diseases like cancer and neurodegeneration.
Area of Science:
- Cell Biology
- Biochemistry
- Physiology
Background:
- Intracellular calcium signaling is vital for cellular functions.
- Store-operated calcium entry (SOCE) generates calcium signals in non-excitable cells.
- Dysregulation of SOCE is implicated in various pathophysiological conditions.
Purpose of the Study:
- To review the regulatory mechanisms of SOCE.
- To summarize proteins that modulate SOCE.
- To highlight SOCE's role in diseases.
Main Methods:
- Literature review of studies on SOCE.
- Analysis of regulatory proteins and mechanisms.
- Examination of SOCE's involvement in diseases.
Main Results:
- SOCE is mediated by Orai1 and STIM1.
- Glycosylation, pH sensing, and specific proteins (golli, α-SNAP, SARAF, ORMDL3, CRACR2A, TRPM4) regulate SOCE.
- Altered SOCE contributes to cancer, immune, and neurodegenerative diseases.
Conclusions:
- Understanding SOCE regulation is crucial for cellular health.
- Identifying SOCE modulators offers therapeutic potential for various diseases.
- This review consolidates current knowledge on SOCE regulation and its disease relevance.
