RanGTPase, one family of small G protein superfamily, has been widely demonstrated to be involved in transport system between cytoplasm and nucleus. However the knowledge about the function of RanGTPase in immunity remains limited. In this report, Ran gene (named LycRan) cDNA was cloned from the large yellow croaker, Pseudosciaena crocea, a marine fish. The full-length cDNA of LycRan was of 1033 bp, including a 5'-terminal untranslated region (UTR) of 43 bp, 3'-terminal UTR of 338 bp and an open reading frame (ORF) of 648 bp encoding a polypept...
