| pubmed-article:11229814 | pubmed:abstractText | Factor V is a plasma protein essential for blood coagulation. This protein is involved in activated protein C resistance, the most common inherited thrombotic disorder known. We utilized the polymerase chain reaction to clone the porcine factor V gene by generating overlapping clones amplified with primers chosen by comparison with known nucleotide sequences. The porcine factor V cDNA contig encodes a predicted 2258-amino acid protein, making it the largest in comparison to the bovine, human, and murine proteins. Porcine factor V has the highest level of homology with bovine factor V, but also has high levels of conservation of important residues with all the species. Radiation hybrid mapping assigned the porcine factor V gene to chromosome 4. Three-dimensional models of factor V were generated and used to analyze membrane-binding sites in terms of conserved, and therefore likely important residues. | lld:pubmed |
