Characterization and tissue distribution of leptin, leptin receptor and leptin receptor overlapping transcript genes in yellow catfish Pelteobagrus fulvidraco

► The full-length cDNAs of LEP, LEPR and LEPROT were cloned and sequenced in yellow catfish, respectively. ► The characterization of LEP, LEPR and LEPROT was compared between yellow catfish and other animals. ► The distribution profiles of LEP, LEPR and LEPROT were determined in several tissues.
