Description de la cible

Antigen stimulation of immune cells triggers Ca++ entry through Ca++ release-activated Ca++ (CRAC) channels. ORAI1 is a recently identified four-transmembrane spanning protein that is an essential component of CRAC. A missense mutation in this protein in humans is the cause of one fo rm of hereditary severe combined immune deficiency (SCID) which results in ablated T-cell Ca++ entry. It has been suggested that ORAI1 functions as a highly selective Ca++ plasma membrane channel that is gated through interactions with STIM1, the store-activated endoplasmic reticulum Ca++ sensor. ORAI1 often migrates at a higher than expected molecular weight in SDS-PAGE. This antibody is predicted to have no cross-reactivity to ORAI2 or ORAI3.

Background and Purpose- Disturbance of endoplasmic reticulum (ER) Ca2+ homeostasis causes neuronal cell injury in stroke. By contrast, ischemic preconditioning (IPC)-a brief sublethal ischemic episode affording tolerance to a subsequent ischemic insult-restores ER Ca2+ homeostasis. Under physiological conditions, ER calcium

Senescence-related fibrosis contributes to cardiac dysfunction. Profibrotic processes are Ca2+ dependent. The effect of aging on the Ca2+ mobilization processes of human ventricular fibroblasts (hVFs) is unclear. Therefore, we tested whether aging altered intracellular Ca2+ release and store-operated Ca2+ entry

Excessive cardiac fibrosis, characterized by increased collagen-rich extracellular matrix (ECM) deposition, is a major predisposing factor for mechanical and electrical dysfunction in heart failure (HF). The human ventricular fibroblast (hVF) remodeling mechanisms that cause excessive collagen deposition in HF are

Defective Ca2+ handling is a key mechanism underlying hepatic endoplasmic reticulum (ER) dysfunction in obesity. ER Ca2+ level is in part monitored by the store-operated Ca2+ entry (SOCE) system, an adaptive mechanism that senses ER luminal Ca2+ concentrations through the
