| Research Abstract |
Cch1 is a yeast homologue of the pore-forming α1 subunit of animal voltage-gated calcium channels (VGCC), and Mid1 is an essential component together with Cch1 for the high-affinity calcium uptake in yeast. We tried to detect electric currents through the Cch1/Mid1 channel expressed in cultured mammalian cells or in yeast spheroplasts by the patch-clump method. Mid1 is heavily N-glycosylated allover the length, and Mid1 has a cysteine-rich motif in the C-terminal region. These characteristics suggest that Mid1 is a functional homologue of the α_2/δsubunit of animal VGCCs.
