Orai2 Products

Description

STIM-Orai channels have recently been identified as the underlying molecular mechanism of store-operated calcium entry(SOCE). SOCE allows rapid Ca2+ efflux from the endoplasmic reticulum (ER), following the emptying of intracellularCa2+ stores. STIM (sensors stromal interaction molecule) proteins, STIM1 and STIM2, serve as ER Ca2+ sensors. Theycontain N'-terminal Ca2+-sensing EF-hand domains and are localized to the tubular ER. Following Ca2+ store depletion,STIMs rapidly cluster and relocalize to the plasma membrane-adjacent ER regions, where they oligomerize and form'puncta'. Orai proteins, Orai1, Orai2 and Orai3, are STIM binding partners that form the pore of the channel. Oraiproteins are uniformly distributed in the plasma membrane and exist as dimers in the resting state. STIM activationinduces tetramerization of Orai proteins and subsequent STIM-Orai colocalization, which forms the activestore-operated calcium channel
