General description

TRP (transient receptor potential)-related ion channels (TRPCs) have been postulated as candidates for forming both receptor-operated (ROCE) and capacitative Ca2+ entry channels across the plasma membrane. ER transmembrane protein STIM1 senses the depletion of Ca2+ from ER stores. Orai, a regulatory β-subunit of the TRPC ion channel α-subunit, transduces the STIM1 signal into activation of the TRPC. Thus, Orai proteins by interacting with TRPCs act as regulatory subunits that confer STIM1-mediated store depletion sensitivity to these channels and regulate Ca2+ influx through the plasma membrane.

Specificity

ORai1, intracellular. Detects both the glycosylated and unglycosylated forms of ORai1. By Western blot the antibody reacts with the ~ 50 kDa ORai1 protein. Additional bands between 35 and 50 kDa may be seen if analyzing overexpressed ORai1. These additional bands most likely represent different degrees of glycosylation of ORai1

Immunogen

Synthetic Peptide from the Intracellular domain of Orai1

Immunoblotting: 1:1,000-1:5,000

Emerging evidence indicates that Orai1, a key calcium channel for store-operated Ca2+ entry, is associated with human cancer. However, the underlying mechanism by which Orai1 regulates cancer progression remains unknown. Here we report that intracellular level of Orai1 is increased
