1.A.87.1.1
Plant Ca2+ channel protein, Mid1 complementary activity 1, MCA1 (Iida et al. 2013).  MCA1 and MCA2 each forms a homotetramer and exhibit Ca2+-permeable MS channel activity.  Both are single-pass type I transmembrane proteins with 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).
