In this Letter, Fig. 1c and e contained errors, which are corrected in Fig. 1 of this Corrigendum. In the key of Fig. 1c, the extracellular conditions for the Ba2+ and NMDG currents were wrongly listed: the purple trace should be BaCl2 (not RbCl) and the grey trace should be NMDG (not BaCl2). This correction accurately reflects the selectivity of the channel as stated on page 315, which should have cited Fig.1c, rather than Fig. 1d, as follows: “The outwardly rectifying current was cation-non-selective (Fig. 1c) with relative permeabilities of Ca2+ ≈ Ba2+ > Na+ ≈ K+ > NMDG”. In Fig. 1e, the channel density for the primary cilia (red bar labelled ‘PKD1L1/2L1’) was wrong, owing to an incorrect estimation of open probability for the channel (0.015 instead of 0.067). This correction reduces the estimated channel density to a value (29 channels per μm2) that is about 4.5 times smaller than the value we initially reported in Fig. 1 and on page 315 (128 channels per μm2). This error does not alter the key findings of Fig. 1e (that the cilia are densely populated with PKD1L1/2L1 channels) or the main conclusions of the Letter.
