Isolation, molecular characterization of cysteine sulfinic acid decarboxylase (CSD) of red sea bream Pagrus major and yellowtail Seriola quinqueradiata and expression analysis of CSD from several marine fish species

Expression analysis of CSD from red sea bream, Japanese seabass, barfin flounder and yellowtail indicated that CSD is expressed in a variety of tissues but commonly in the liver and pyloric ceca of all species examined. Additionally, strong CSD expression was observed in the heart in all species examined except for Japanese seabass.
