Comparative gene expression analysis of the fmnl family of formins during zebrafish development and implications for tissue specific functions

► Phylogenetic relationships between Fmnl Formins, conserved catalysts of linear actin. ► Fmnls are maternally provided and widely expressed in early zebrafish embryos. ► Histological analysis of zebrafish fmnls shows distinct and common expression domains. ► Fmnls show tissue specific expression in the vascular, visual and otic systems.
