High polymorphism in Plasmodium vivax merozoite surface protein-5 (MSP5).

abstract：:Voltage-gated calcium (Ca2+) channels contribute to impulse propagation in excitable cells and also regulate intracellular levels of Ca2+. High voltage-activated (HVA) Ca2+ channels are heteromultimeric membrane proteins. The pore-forming, voltage-sensing subunit is the alpha1 subunit. We have cloned 3 HVA Ca2+ channe...
