There was an error published in Journal of Experimental Biology (2020) 223, jeb215111 (doi:10.1242/jeb.215111).

In Materials and Methods, ‘Morpholino KD’, the morpholino sequence targeting slc9a3.2 (Nhe3b) was incorrectly written as 5′-CAGTTGCCCATGTCTACAGCTTGAG-3′. The correct sequence of the injected Nhe3b morpholino is 5′-AGTAGAAAACGCCATATCAGAACGC-3′. Both the online full-text and PDF versions of the article have been updated.
