Tertiapin LQ, a peptide derivative of honeybee venom peptide tertiapin, acts as an inhibitor of inwardly rectifying potassium (Kir) channels. Specifically, it targets and inhibits heteromultimeric potassium channels, including those formed by GIRK1 (also known as Kir3.1) and GIRK4 (Kir3.4), as well as inward-rectifier potassium channel 1 (Kir1.1). Its efficaciousness extends to in vivo applications, where it has been observed to suppress the Purkinje cell pause response to conditional stimuli in ferrets.
