摘要：

Here we show evidence that S-adenosyl-L-homocysteine hydrolase (SAHH) is linked to the actin cytoskeleton. Actin rods formed in Dictyostelium discoideum spores during the final stage of development are structurally composed of novel bundles of actin filaments. SAHH only accumulates with actin at this stage of development in the life cycle of D. discoideum. Recently SAHH is believed to be a target for antiviral chemotherapy and the suppression of T cells. Our finding may contribute to designing novel antiviral and immunosuppressive drugs. (C) 2001 Federation of European Biochemical Societies. Published by Elsevier Science B.V. All rights reserved.
