['To determine AF172993 sequence is either the complete CDS or a transcript variant.', 'RT-PCR was used to amplify the CDS sequence of Plunc, which was subsequently cloned into the pEGFP-N1 eukaryotic expression vector. After bi-directional sequence analysis, the sequence obtained was blasted against the AF172993 sequence, nr database and human genome database.', 'In CDS of the new cloned sequence, the 658 base A in the AF172993 sequence was replaced by C, and the corresponding genetic code was also converted from AAG to CAG, leading to the alteration of the amino acid Gln to Lys. In addition, the base C at the 658 position of the CDS showed perfect match with the base C at 2094188 position in human chromosome 20.'] Is [ AF172993 sequence of Plunc in GenBank database the complete CDS ]?
