Molecular mechanism of Zn2+ inhibition of a voltage-gated proton channel #MMPMID27647906
Proc Natl Acad Sci U S A 2016[Oct]; 113 (40): E5962-71 PMID27647906show ga
Zn2+ inhibition of voltage-gated proton (Hv1) channels has important physiological roles, such as quiescence of sperm in the male reproductive system. Here, we show that Zn2+ binds to different states of Hv1, and we propose a possible mechanism for Zn2+ inhibition of Hv1. Several residues are found to be involved in Zn2+ binding, and we provide detailed information about how these residues contribute to the functional effect of Zn2+ binding. This study provides valuable information for future drug development for Hv1 channels.
