Reaction: CRAC translocates calcium from the extracellular region to the cytosol

- in pathway: Antigen activates B Cell Receptor (BCR) leading to generation of second messengers
Activation of Calcium-release-activated (CRAC) channels allows influx of calcium. The Orai component of CRAC is responsible for the selectivity of the channel, while the Stim component is responsible for activation.
