WebThe bilayer lipid membrane (BLM) is the main structural component of cell membranes, in which various membrane proteins are embedded. Artificially formed BLMs have been used as a platform in studies of the functions of membrane proteins, including various ion channels. In this review, we summarize recent advances that have been made on … WebPotassium channelopathies on a genetic basis are associated with an epilepsy phenotype. Recently, a mutation in the Kv4.2 gene leading to a truncation of the carboxyl-terminus has been described in TLE. In addition, defects in the gene encoding an auxiliary subunit for Kv4.x channels, Kvβ2, have been described in human developmental epilepsy.
