Abstract

The Ca(2+) sensor STIM1 and the Ca(2+) channel ORAI1 are the fundamental working machinery of the CRAC channel, a classical pathway for store-operated Ca(2+) entry. This chapter focuses on the protein-protein interactions of STIM and ORAI proteins that control the channel.

KEYWORDS:

CRAC channel; CRAC current; ORAI1; ORAI3; STIM1; calcium; gating; interaction; mutation; protein; store-operated calcium entry; structure
