Using GAL4-Inducible Transgenics to Modulate Rho GTPase Activity in Zebrafish

Methods Mol Biol. 2018:1821:359-370. doi: 10.1007/978-1-4939-8612-5_24.

Abstract

Rho GTPases are Ras-family G proteins that regulate many critical cellular functions. Due to their requirement during early embryonic development, investigations into the function of Rho GTPases at a tissue-specific level require inducible and spatially targeted modulation of Rho GTPase activity. Here, we describe the use of ten novel zebrafish transgenics enabling GAL4-specific expression of Rho GTPases to modulate Rho GTPase activity with spatial and temporal control.
