    ABSTRACT: Rhesus monkeys (Macaca mulatta) are human's closest evolutionary relatives next to Chimpanzees, and they are widely used in biomedical researches. Analyses of the rhesus monkey trasnscriptome and the sequence divergence between monkey and human are of importantce to the development of scientific analyses and to the application and interpretation of the results from animal experiments. In this study, we analyzed the genetic and transcriptional information. Four hundred and one clones were randomly selected from a liver tissue cDNA library of rhesus monkey, and the expressed sequence tags (ESTs) were sequenced. We acquired 393 effective ESTs that were assembled into 221 Unigenes with Phrap software. Alignments of the sequences showed that 188 Unigenes matched with known proteins in Swiss_prot database, of which 16 Unigenes matched the known rhesus proteins, and 171 Unigenes had high homology with human proteins. Then the result of BLASTN comparison showed that 26 of another 33 Unigenes matched the known rhesus genes. Finally, the remaining Unigenes were aligned in dbEST and rhesus genome database, and the results suggested 3 Unigenes be newly discovered ESTs of rhesus.

    ABSTRACT: FVII is a vitamin K dependent serine protease that plays a key role in extrinsic coagulation pathway. In this paper, we report the full-length cDNA sequences of rhesus monkey FVII. The full-length cDNA has 2424 bp, and predicts an open reading frame of 1416 bp corresponding to 472 amino acids. The deduced protein sequence of rhesus monkey FVII indicates the functional domains including signal peptide, Gla domain, two EGF domains, and catalytic domain. Rhesus monkey FVII is highly homologous to human FVII with amino acid identity of 91.0%. Comparison of three-dimensional protein structure shows high conservation between them. The important functional sites such as the N-terminal gamma-carboxyglutamic acids of the Gla domain, the Ca(2+) binding region of the EGF I domain, the TF binding region, the active site binding cleft, and the macromolecular substrate binding exosite of trypsin domain are all well conserved in FVII of rhesus monkey. Prothrombin time test shows rhesus monkey FVII has a similar clotting time with that of human. This study of rhesus monkey FVII might be helpful for understanding the function compatibility of human and rhesus monkey FVII, which is beneficial for the study of xenotransplantation.
