The unique gene, pleiotrophin (ptn) was identified in the expressed sequence taq (EST) derived from the developing tilapia brain in our lab. The cDNA full length of ptn was cloned. ptn play a role in the differentiation of nerve cell. In this study, bioinformatics were searched for EE723939.1 (ptn), which is a gene with 1026 bp of cDNA sequence, open reading frame(ORF) is 483bp, and deduced as 160 amino acids. The protein of PTN was expressed in the prokaryotic system, BL21(E.coli), and purified with Ni-NTA affinity chromatography. In the present studies, ptn, cloned from tilapia, Oreochromis mossambicus. The influence of ptn on the proliferation of Neuro-2a cell was also investigated.The ORF of ptn was cloned, and the pEGFP-ptn plasmid was constructed. The distribution of ptn in the pEGFP-ptn transfected Neuro-2a cell was identified by fluorescence and laser confocal microscopy.
