Lingfeng's work on the ion permeation and selectivity mechanisms of the voltage-gated calcium ion channel CaV1 has been published in PNAS (Link). In this work, Lingfeng showed that the three-ion knock-on mechanism not only enables the efficient calcium ion permeation but also helps to generate the valence selectivity because it is harder for sodium ions to get involved in the knock-on. Congratulations!
