1.A.87.1.2
Plant Ca2+ channel protein, Mid1 complementary activity 2, MCA2 (Iida et al. 2013).  Catalyzes mechanical stress-induced Ca2+ influx.  It is tetrameric with a small transmembrane domain and a large cytoplasmic domain (Shigematsu et al. 2014).  MCA1 and MCA2both have their N-termini located extracellularly and their C-termini located intracellularly. An EF hand-like motif, coiled-coil motif, and plac8 motif may all be in the cytoplasm, suggesting that the activities of both channels can be regulated by intracellular Ca2+ and protein interactions (Kamano et al. 2015).
