Abstract:
To look for new genes from human brain, get a fragment was obtained using adaptor primer and 3' anchor polymerase chain reaction (PCR) with the human adult whole brain cDNA as template. The fragment was cloned into T easy vector and automatically sequenced with 310 Genetic Analyzer. Later the whole length cDNA of this novel gene was got with the method of 3'rapid amplification of cDNA end (RACE). The whole length of cDNA of this novel gene is 2 024 bp. Chromsome location is at 14q11.2 including 16 extrons and 15 introns. After scanning the sequence against GenBank it is proved that the sequence is a new one. ORF analysis showed that there is a complete coding region in it,it can interprate a protein containing 357 amino acid residules. ProDom analysis result showed that there is an acyl carrier protein (ACP) like domain in it. The gene was banked into GenBank. Then, a pare of primers were designed and were used to amplify the coding region and cloned into pGEX-4T1 expressing vector to express it in E. coli . The Dot blotting and Northern blot showed that this novel gene is highly expressed in the normal adult human brain.
