Abstract
In this study, we determined the interaction between TM4 and TM2/TM3 domain of Solute carrier family 11 member 1 (Slc11a1) by circular dichroism (CD) and fluorescence spectrum. The results indicated that, the cation transport process was likely to be accomplished by the collaboration of multiple TM domains rather than by TM4 domain alone. Therefore, this finding suggested possible transportation theory and be helpful to elucidate the mechanism of Slc11a1 in cation transport process.
