ORAI Calcium Channels: Regulation, Function, Pharmacology, and Therapeutic Targets
Pharmaceuticals, 2023 The changes in intracellular free calcium (Ca2+) levels are one of the most widely regulators of cell function; therefore, calcium as a universal intracellular mediator is involved in very important human diseases and disorders.

Structural Insights into Ca2+ Permeation through Orai Channels
Cells, 2021 Orai channels belong to the calcium release-activated calcium (CRAC) channel family. Orai channels are responsible for the influx of extracellular Ca2+ that is triggered by Ca2+ depletion from the endoplasmic reticulum (ER); this function is essential ...

Notch1 regulates Orai1 and Orai3 expression in breast cancer cells [PDF]
Scientific ReportsStore-operated Ca²⁺ entry (SOCE) is a major pathway for Ca²⁺ entry that regulates several cellular functions. SOCE remodeling mediated by changes in the expression and/or function of the Orai channels results in the reorganization of intracellular Ca2 ...

Mechanistic insights into Orai dynamics during pore opening [PDF]
ChannelsOrai channels form highly Ca2+-selective pores in the plasma membrane (PM) and represent one of the two essential components of the Ca2+ release-activated Ca2+ (CRAC) channel.

Research progress on the role and mechanism of STIM and Orai protein-mediated store-operated calcium entry in cardiovascular diseases [PDF]
ChannelsStore-operated calcium entry (SOCE) mediated by STIM and Orai proteins is a fundamental Ca2+ influx mechanism that critically regulates intracellular calcium homeostasis and participates in cardiovascular pathophysiology.

Electromyography Scanning in the Diagnosis of Tension Headache [PDF]
Journal of Clinical and Diagnostic Research, 2021 Introduction: Several attempts have been made to validate the purported aetiological mechanism after the prescribed proposal by the Ad Hoc Committee (1962), on the Classification of Headache which was recognised as muscle contraction or tension as a ...

High affinity associations with α-SNAP enable calcium entry via Orai1 channels
PLoS ONE, 2021 Molecular steps that activate store-operated calcium entry (SOCE) via Orai channel supramolecular complex remain incompletely defined. We have earlier shown that α-SNAP regulates the on-site functional assembly and calcium selectivity of Orai1 channels ...
