Molecular insights into electroreceptor ribbon synapses from differential gene expression in sturgeon lateral line organs. [PDF]

open access: yesJ Anat
The expression of various genes involved in synapse development, stability and/or function was studied in developing mechanosensory neuromasts and electrosensory ampullary organs in sterlet sturgeon. Most were shared, including Slc17a8, Slc1a3 and Nrxn3, but Cbln18 was neuromast‐restricted and Tulp1 was ampullary organ‐restricted.
