Research Abstract |
Ion channel proteins work for selective permeation of ions in response to various stimuli and regulate electrical signals in living organisms. To understand the molecular mechanisms of these channels, the precise structural information with atomic resolution is required. In this study, mammalian ion channel proteins, which are important targets in medical and pharmaceutical sciences, have been studied by attenuated total reflection (ATR) FT-IR spectroscopy which gives us precise molecular information. After screening of several ion channel proteins, we have succeeded to resolve amide I bands of selectivity filter of KCNK1 channel, which is involved in regulation of resting membrane potential of cell, by using ATR FT-IR spectroscopy.
