Cloning and Phylogenetic Analysis of the Ribosomal Protein L8 cDNA of the Weever(Lateolabrax japonicus) / 现代生物医学进展

ABSTRACT

The complete nucleotide sequence of a cDNA clone encoding weever ribosomal protein L8, WeevL8, is described here. The WeevL8 cDNA has 848 nucleotides in full length and encodes a 257 amino-acid protein with a calculated molecular mass of 28.02 kDa. Two conserved domains have been identified in WEEVL8. It was concluded fromsequence alignment that WeevL8 gene was quite conservative, consistent with its role as a house-keeping gene. A phylogenetic analysis made by L8 protein showed the similar phylogenetic relationship to that with 18s rDNA. The high similarity supports the notion that ribosomal protein L8 can also be used as phylogenetic criterion.
