Extended Data Fig. 8. ttn.1-null zebrafish shows a severe skeletal muscle phenotype.

Extended Data Fig. 8

af, Lateral view of Alexa Fluor phalloidin filamentous actin (green) and α-actinin Z-band marker (red) staining in skeletal fast muscle fibers in wild-type (a,d), srpk3+/+;ttn.1/ (b,e) and srpk3/;ttn.1/ (c,f) larvae at 5 dpf. Compared to wild-type fish (a,d), the muscle fiber structure was largely lost in the ttn.1-null zebrafish, regardless of the srpk3 status (that is both srpk3+/+;ttn.1/ and srpk3/;ttn.1/). Scale bars are 25 µm. Representative images from >15 pooled fish per genotype.
