Hetero-oligomeric TRP-like channels such as PKD1L3/PKD2L1 play crucial roles in a range of physiological and pathophysiological processes. Here, the authors present the cryo-EM structures of a minimal functional murine PKD1L3/PKD2L1 complex in the absence and presence of calcium and further supported through structure-guided mutagenic studies, they discuss the mechanism of calcium-induced channel activation.
