Calsequestrin-1 Regulates Store-Operated Ca2+ Entry by Inhibiting STIM1 Aggregation

open access: yesCellular Physiology and Biochemistry, 2016
Background/Aims: Stromal interacting molecule-1 (STIM1) aggregation and redistribution to plasma membrane to interact with Orai1 constitute the core mechanism of store-operated Ca2+ entry (SOCE).

The STIM1–ORAI1 microdomain [PDF]

open access: yesCell Calcium, 2015
The regulatory protein STIM1 controls gating of the Ca(2+) channel ORAI1 by a direct protein-protein interaction. Because STIM1 is anchored in the ER membrane and ORAI1 is in the plasma membrane, the STIM-ORAI pathway can support Ca(2+) influx only where the two membranes come into close apposition, effectively demarcating a microdomain for Ca(2 ...

Regulation of STIM1 and SOCE by the ubiquitin-proteasome system (UPS).

open access: yesPLoS ONE, 2010
The ubiquitin proteasome system (UPS) mediates the majority of protein degradation in eukaryotic cells. The UPS has recently emerged as a key degradation pathway involved in synapse development and function.

TRPC Channels in the SOCE Scenario

open access: yesCells, 2020
Transient receptor potential (TRP) proteins form non-selective Ca2+ permeable channels that contribute to the modulation of a number of physiological functions in a variety of cell types. Since the identification of TRP proteins in Drosophila, it is well

STIM1 Deficiency In Intestinal Epithelium Attenuates Colonic Inflammation and Tumorigenesis by Reducing ER Stress of Goblet CellsSummary

open access: yesCellular and Molecular Gastroenterology and Hepatology, 2022
Background & Aims: As an indispensable component of store-operated Ca2+ entry, stromal interaction molecule 1 (STIM1) is known to promote colorectal cancer and T-cell–mediated inflammatory diseases.

Insights into Activation Mechanisms of Store-Operated TRPC1 Channels in Vascular Smooth Muscle

open access: yesCells, 2020
In vascular smooth muscle cells (VMSCs), the stimulation of store-operated channels (SOCs) mediate Ca2+ influx pathways which regulate important cellular functions including contraction, proliferation, migration, and growth that are associated with the ...

STIM1-dependent peripheral coupling governs the contractility of vascular smooth muscle cells

open access: yeseLife, 2022
Peripheral coupling between the sarcoplasmic reticulum (SR) and plasma membrane (PM) forms signaling complexes that regulate the membrane potential and contractility of vascular smooth muscle cells (VSMCs).

Plasma Membrane and Organellar Targets of STIM1 for Intracellular Calcium Handling in Health and Neurodegenerative Diseases

open access: yesCells, 2021
Located at the level of the endoplasmic reticulum (ER) membrane, stromal interacting molecule 1 (STIM1) undergoes a complex conformational rearrangement after depletion of ER luminal Ca2+.

POST, partner of stromal interaction molecule 1 (STIM1), targets STIM1 to multiple transporters [PDF]

open access: yesProceedings of the National Academy of Sciences, 2011
Specialized proteins in the plasma membrane, endoplasmic reticulum (ER), and mitochondria tightly regulate intracellular calcium. A unique mechanism called store-operated calcium entry is activated when ER calcium is depleted, serving to restore intra-ER calcium levels.
