Literature

Swapping of transmembrane domains in the epithelial calcium channel TRPV6.

Singh, A.K.Saotome, K.Sobolevsky, A.I.

(2017) Sci Rep 7: 10669-10669

  • PubMed Abstract: 

    Tetrameric ion channels have either swapped or non-swapped arrangements of the S1-S4 and pore domains. Here we show that mutations in the transmembrane domain of TRPV6 can result in conversion from a domain-swapped to non-swapped fold. These results reveal structural determinants of domain swapping and raise the possibility that a single ion channel subtype can fold into either arrangement in vivo, affecting its function in normal or disease states.
