KV10.1 Background Information

KV10.1, also known as human ether à-go-go1 protein or EAG1, is the pore-forming (alpha) subunit of a voltage-gated delayed rectifier potassium channel. Upon a depolarization, a slowly activating noninactivating outward current is elicited. Upon repolarization a small tail current occurs. EAG1 is expressed almost exclusively in brain tissue and is involved in cell excitability, memory processes, and cell proliferation. Their expression in over 70% of human tumours makes them an attractive diagnostic and therapeutic target treatment of prostate cancer: The Eag1 K+ channel is especially thought to be involved in the pathophysiological processes of prostate cancer, and is expected to be a valuable target for the diagnosis and treatment of prostate cancer.
