Fig. 1. Structure and developmental expression of the leiomodin (Lmod) and tropomodulin (Tmod) gene families. (A) leiomodin (Lmod1–3) and tropomodulin (Tmod1–4) proteins are structurally related, yet possess unique domains. Lmods and Tmods share actin-binding (A1, A2), tropomyosin-binding (TM1) and leucine-rich-repeat (LRR) domains. A second tropomyosin-binding domain (TM2) is unique to the Tmods. Lmod proteins have a Cterminal extension that contains a third actin binding/WH2 domain (WH2/A3). (B–I) Lmod (C–E) and Tmod (F–I) family gene expression was analyzed during Xenopus embryonic development using in situ hybridization. All embryos are positioned with heads to the left. Expression patterns are shown at the early tailbud stage (st30), during the early stages of myofibrillogenesis. Earlier expression during the neurula stage (st15) is presented in supplementary material Fig. S1. Expression of the definitive striated muscle marker cardiac actin, actna1 (B), was used to indicate cardiac and skeletal muscle tissue in the embryo. Arrows indicate developing skeletal muscle and heart tissues. Only lmod3 (E) and tmod4 (I) are expressed at high levels in developing skeletal muscle.
