Abstract
The microinjection of mRNA that is transcribed and capped in vitro into fertilized eggs and embryos of Xenopus laevis provides a powerful means for discovering the function of proteins during early development. Proteins may be overexpressed for a gain-of-function effect or exogenous protein function may be compromised by the microinjection of mRNA encoding “dominant-negative” proteins. This methodology is particularly suited for the investigation of the regulation of the cell cycle, checkpoints, and apoptosis in early development.
