Abstract
The most common way to analyze the function of cloned genes in zebrafish is to misexpress the gene product or an altered variant of it by mRNA injection. However, mRNA injection has several disadvantages. The GAL4-UAS system for targeted gene expression allows one to overcome some of these disadvantages. To test the GAL4-UAS system in zebrafish, we generated two different kinds of stable transgenic lines, carrying activator and effector constructs, respectively. In the activator lines the gene for the yeast transcriptional activator GAL4 is under the control of a given promoter, while in the effectors the gene of interest is fused to the sequence of the DNA-binding motif of GAL4 (UAS). Crosses of animals from the activator and effector lines show that effector genes are transcribed with the spatial pattern of the activators. This work smoothes the way for a novel method of misexpression of gene products in zebrafish in order to analyze the function of genes in developmental processes.
