abstract：:An 18.2 kDa protein from the liver fluke, Fasciola hepatica has been identified and characterised. The protein shows strongest sequence similarity to egg antigen proteins from Schistosoma mansoni, Schistosoma japonicum and Clonorchis sinensis. The protein is predicted to adopt a calmodulin-like fold; it thus represent...
