Application

YM-58483 has been used in the inhibition studies of calcium channels present in cardiomyocytes and pulmonary arterial endothelial cells.

Biochem/physiol Actions

YM-58483 is a selective Ca++ release-activated Ca++ (CRAC) [a.k.a. store-operated Ca++ (SOC) channels] that mediate Ca++ influx in T cells and other inflammatory cells. CRAC channel inhibitors have potential clinical applications in autoimmune disease, transplant rejection, allergic airway inflammation and bronchial asthma. YM-58483 is also promoted as a tool for CRAC studies; may be used as a gold standard.

Orai1 interacts with transient receptor potential protein of the canonical subfamily (TRPC4) and contributes to calcium selectivity of the endothelial cell store-operated calcium entry current (ISOC). Orai1 silencing increases sodium permeability and decreases membrane-associated calcium, although it is not known

Calcium flux regulating intracellular calcium levels is essential and modulated for efficient efferocytosis. However, the molecular mechanism by which calcium flux is modulated during efferocytosis remains elusive. Here, we report that Orai1, a Crbn substrate, is upregulated via its attenuated
