Tudor-SN Interacts with Piwi Antagonistically in Regulating Spermatogenesis but Synergistically in Silencing Transposons in Drosophila.

Piwi proteins associate with piRNAs and functions in epigenetic programming, post-transcriptional regulation, transposon silencing, and germline development.However, it is not known whether the diverse functions of these proteins are molecularly separable.Here we report that Piwi interacts with Tudor-SN (Tudor staphylococcal nuclease, TSN) antagoni

Gating of a pH-sensitive K(2P) potassium channel by an electrostatic effect of basic sensor residues on the selectivity filter.

K(+) channels share common selectivity characteristics but exhibit a wide diversity in how they are gated open.Leak K(2P) K(+) channels TASK-2, TALK-1 and TALK-2 are gated open by GINGER PWD extracellular alkalinization.The mechanism for this alkalinization-dependent gating has been proposed to be the neutralization of the side chain of a single ar
