Molecular Characterization and Expression Profiles of Sp-uchl3 and Sp-uchl5 during Gonad Development of Scylla paramamosain

Ubiquitin C-terminal hydrolases (UCHLs) are a subset of deubiquitinating enzymes, and are involved in numerous physiological processes. However, the role of UCHLs during gonad development has not been studied in crustaceans. In this study, we have first cloned and analyzed expression profiling of Sp-uchl3 and Sp-uchl5 genes from mud crab Scylla paramamosain. The full-length cDNA of Sp-uchl3 is of 1804 bp. Its expression level in the ovary was significantly higher than in other tissues (p 0.05). These results provide basic data showing the role of Sp-UCHL3 and Sp-UCHL5 in the gonad development of the crab.
