TRPM7_tetra is a short anti-parallel coiled-coil tetramerisation domain of the transient receptor potential cation channel subfamily M member proteins 1-8. It is held together by extensive core packing and interstrand polar interactions. Transient receptor potential (TRP) channels comprise a large family of tetrameric cation-selective ion channels that respond to diverse forms of sensory input. The presence of cytoplasmic domains that direct channel assembly appears to be a feature of many voltage-gated ion channel superfamily members [1].	Domain
