Characterization of zebrafish full-length prothrombin cDNA and linkage group mapping.

In this paper, we report the complete cDNA sequence of zebrafish prothrombin. The cDNA sequence predicts that zebrafish prothrombin is synthesized as a pre-proprotein consisting of a Gla domain, two kringle domains, and a two-chain protease domain. Zebrafish prothrombin is structurally very similar to human and other vertebrate prothrombins. Zebrafish and human prothrombin share 53% amino acid identity whereas zebrafish and hagfish prothrombin share 51% identity. Amino acid alignments of various prothrombins identified conservation of many of the functional/structural motifs suggesting that the vertebrate prothrombins may have similar functions. The three-dimensional structure of prothrombin predicted by homology modeling also revealed that the prothrombin fragment 1 and the catalytic domain structures are well conserved except for the insertion of an extra 7-amino-acid loop in the connecting region (CR) between the Gla and kringle I domain of fragment 1. Linkage analysis revealed that the prothrombin gene locus on linkage group 7 in zebrafish is syntenic to the human chromosome 11-prothrombin region suggesting its preservation through evolution. The availability of this cDNA sequence in zebrafish adds to our knowledge of the zebrafish hemostatic system and provides support for the view that similarities between zebrafish and mammalian coagulation exist, thus underscoring the relevance of the zebrafish model for studying human hemostasis.[1]
