- Description
- Predicted to enable inward rectifier potassium channel activity. Acts upstream of or within fin morphogenesis and negative regulation of calcineurin-mediated signaling. Predicted to be located in membrane. Predicted to be part of monoatomic ion channel complex. Predicted to be active in plasma membrane. Is expressed in several structures, including digestive system; fin; gill; heart; and immune system. Human ortholog(s) of this gene implicated in long QT syndrome; long QT syndrome 2; and short QT syndrome. Orthologous to human KCNH2 (potassium voltage-gated channel subfamily H member 2).
