Partial GH cDNA of the rohu (3′-end) was amplified by RT-PCR and used as probe to screen the cDNA library. Full-length GH-specific cDNA clones (1180 bp) were isolated and sequenced. The sequence contains 48-bp 5′-noncoding region followed by an ORF of 621 bp and a 3′-noncoding region of 521 bp. The peptide shares about 90% identity with the GH of Cyprinus carpio (Linn.) and >84% identity with GH sequences of other cyprinids. The GH-encoding cDNA of rohu has been cloned into expression vectors and GH protein has been over expressed in Escherichia coli and purified as a soluble protein. The GH cDNA was cloned into a bicistronic vector with EGFP; injection of in vitro transcribed GH-EGFP mRNA into zebrafish embryo has resulted in EGFP expression confirming the cloned GH cDNA is functional in fish and the IRES element could be effectively used in fish for bicistronic expression of foreign genes. © 2002 Elsevier Science (USA).||Source Title:||General and Comparative Endocrinology||URI:||http://scholarbank.nus.edu.sg/handle/10635/133335||ISSN:||00166480||DOI:||10.1006/gcen.2001.7759|
