Floating head (Flh) is a zebrafish homeobox gene critical to notochord development, and is one of the earliest genes to be expressed in notochord precursors. Studies have shown that Flh is critical to epiphysial neurogenesis, glomerular differentiation, axial vascular development and other key elements of zebrafish growth. Zebrafish Flh mutants develop without a notochord, but still develop with mesodermal derivatives such as the prechordal plate. In Flh mutants, Flh RNA is expressed at lower levels, suggesting a mechanism of positive self-regulation. Flh is a homologue of the homeobox gene Xnot in amphibians.
