"Notably, I KS activity is tightly regulated by PKA-dependent phosphorylation, and this phosphorylation is tuned by both local PKA and PP1 signaling cascades. xref In heart, yotiao directly associates with Kv7.1 to recruit both PKA and PP1 to regulate I KS phosphorylation and gating ( xref ). xref Moreover, the LQT1-causative mutation, G589D abolishes Kv7.1’s association with yotiao thereby disrupting the channel’s sensitivity to beta-adrenergic regulation. xref "
