Cross-linking of Orai1 channels by STIM proteins [PDF]
Significance The work presents a unique understanding of the organization and function of two ubiquitously expressed proteins, central in generating calcium signals in all cell types. These are the intracellular calcium sensing “STIM” proteins, and the highly selective cell surface “Orai” calcium channels. We reveal that STIM proteins

STIM2 Induces Activated Conformation of STIM1 to Control Orai1 Function in ER-PM Junctions
Summary: Ca2+ entry mediated by the calcium channel, Orai1, provides critical Ca2+ signals that regulate cell function. The ER-Ca2+ sensor protein, STIM1, recruits and strongly activates Orai1 within ER-PM junctions.

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

Ion Channel Dysfunction and Therapeutic Targeting in Salivary Gland Disorders
ABSTRACT Objective Salivary gland hypofunction and xerostomia represent major clinical complications of radiation therapy, autoimmune disorders such as Sjögren's disease, and inherited epithelial ion transport defects. This review integrates current knowledge on ion channel dysfunction as a central mechanistic driver of salivary gland pathology and ...

Abstract figure legend LIGHT is a mutual mediator of intestinal and oesophageal fibroblast inflammation with common as well as tissue‐specific effects. Hydroxylase inhibitors can selectively suppress inflammatory factors in both cell types, albeit targeting different signalling pathways.

Sestrin2 interacts and regulates Orai1 calcium channels [PDF]
Department of Biological SciencesStore-operated Ca2+ entry (SOCE) is based on the interaction of endoplasmic reticulum (ER) Ca2+ sensor stromal interaction molecule 1 (STIM1) with the Orai1 Ca2+ channel which is located in plasma membrane.

ORAI1 Ca2+ Channels Control Endothelin-1-Induced Mitogenesis and Melanogenesis in Primary Human Melanocytes [PDF]
UV radiation of the skin triggers keratinocytes to secrete endothelin-1 (ET-1) that binds to endothelin receptors on neighboring melanocytes. Melanocytes respond with a prolonged increase in intracellular Ca2þ concentration ([Ca2þ]i), which is ...

Relationship between DOX, p53, and ORAI1 in CFs.
DOX increased the expression of p53 and induced apoptosis, cell cycle arrest, and ROS production. In addition, DOX increased the expression of ORAI1, not STIM1.

Dynamic interaction of SARAF with STIM1 and Orai1 to modulate store-operated calcium entry [PDF]
Ca2+ influx by store-operated Ca2+ channels is a major mechanism for intracellular Ca2+ homeostasis and cellular function. Here we present evidence for the dynamic interaction between the SOCE-associated regulatory factor (SARAF), STIM1 and Orai1.

Aims: The underlying mechanism of diabetic enteropathy, a common complication of type 1 diabetes, remains unclear. Store-operated Ca2+ entry (SOCE) is a ubiquitous type of Ca2+ influx involved in various cellular functions.
