Tropomodulin 4 localization within the fast muscle cell from 17 hpf up to 42 hpf in immotile and control embryos. In control embryos (A–C) Tmod4 is initially located in the nucleus of the fast muscle cell at 17 hpf (orange arrow, insert) (A) and then migrate into the fast muscle cell cytosol at 24 hpf (B) where it stays up to 42 hpf (empty nuclei white arrows, inserts) (C). Tricaine treated immotile embryos (D,E) display a cytosolic localization of Tmod4 at both 24 hpf (D) and 42 hpf (E) (empty nuclei, white arrows, inserts). Recovered motile embryos at 42 hpf (F) display a similar cytosolic localization of Tmod4 as control and treated embryos (empty nuclei, white arrows, inserts). Controls siblings motile embryos (G,H) display a cytosolic localization of Tmod4 from 20 hpf (G) which is maintained up to 42 hpf (H) (empty nuclei, white arrows, inserts). Immotile relaxed mutants embryos (I,J) display a similar cytosolic localization of Tmod4 at both 20 hpf (I) and 42 hpf (J) as control siblings (empty nuclei, white arrows, inserts).
