Abstract: In order to obtain complete sequence and catalytic core of human tyrosine hydroxylase(TH) cDNA,the full length of cDNA from human TH was used as template and the specific oligonucleotide primers were designed for PCR.The target fragments were cloned into vector pGEX-4T-1 respectively.The recombinant plasmids were transferred into E.coli BL21,and the expression of target protein was induced with IPTG.The expressed protein was analysed by SDS-PAGE and western-blotting.The result showed that the cDNA fragments of complete sequence and catalytic core of human TH were harvested.The sequencing for them showed that the cloned target gene fragments were correct.SDS-PAGE indicated that the proteins with Mr about 83000 and 66000 were expressed with the recombinant plamids pGEXTHa and pGEXTHc respectively.

Key words: tyrosine hydroxylase, expression, catalytic core, complete seque
