General description

Highly specific for divalent cations (Ca2+ > Mg2+ >> Sr2+ = Ba2+). More effective than antibiotic A23187 as a mobile ion carrier for Ca2+. Complexes with Ca2+ between pH 7 and 9.5, causing significant absorption in the UV range; however, in contrast to A23187 (Cat. No. 100105), it is not fluorescent. Useful for studies of Ca2+ transport across biological membranes and measurement of cytoplasmic free Ca2+. Induces apoptotic neuronal degeneration in embryonic cortical neurons. Also induces cell cycle arrest in the G1 interval of mature Burkitt lymphoma cell lines.

Biochem/physiol Actions

Sustained activation of the Ca2+-release-activated Ca2+ (CRAC) channel is pivotal for effector T cell responses. The mechanisms underlying this sustainability remain poorly understood. We find that plasma membrane localization of ORAI1, the pore subunit of CRAC channels, is limited in effector
