KCNH7 Membrane Protein Introduction

Introduction of KCNH7

KCNH7 is encoded by the KCNH7 gene. It belongs to the potassium voltage-gated channel subfamily H which has been extensively studied during the past few decades because it offers numerous possibilities for therapeutic applications. It is a member of voltage-gated potassium (Kv) channels subunit, which can regulate the neurotransmitter release, insulin secretion, epithelial electrolyte transport, and neuronal excitability. Meanwhile, recent studies have identified that KCNH7 is associated with various diseases such as bipolar spectrum disorder and hypotonia, which indicates KCNH7 could be a target for clinical therapy.

Function of KCNH7 Membrane Protein

KCNH7 is a member of pore-forming (alpha) subunit. Previous studies have shown that it has high expression in several tissues, such as brain, testis, and liver, which suggests it could be involved in tissue regulation and progression. It has at least two transcriptional variants to encode different isotopes. In addition, studies have confirmed that KCNH7 plays an important role in the regulation of autophagy in a cancer cell model. Meanwhile, the expression of KCNH7 is a functional marker for brain activity including responses to novelty, sustained wakefulness, and sleep.

Clegern W.C., et al. Sleep Homeostatic and Waking Behavioral Phenotypes in Egr3-Deficient Mice Associated with Serotonin Receptor 5-HT₂ Deficits. Sleep. 2016, 39(12): 2189-2199. PubMed ID: 28057087

This article analyzes the expression levels of Egr3 in regulating wakefulness and sleep in mice. The results show that Egr3 can interact with 5-HT2 receptors to further regulate cortical arousal, wakefulness, and sleep of mice.
Perez-Neut M., et al. Activation of hERG3 channel stimulates autophagy and promotes cellular senescence in melanoma. Oncotarget. 2016, 7(16): 21991-2004. PubMed ID: 26942884

This article reports that hERG3 plays a critical role in the regulation of autophagy in a cancer cell model. NS1643 can activate the AMPK-dependent signaling pathway to stimulate the Kv11.3 channel, which provides a novel therapeutic approach against melanoma.
