title: Engineering mutations: deconstructing the mouse gene by gene.
abstract: Over the past years new vectors and methodologies have been developed to carry out large-scale genome-wide insertional mutagenesis screens in the mouse. Gene trapping, the most commonly used technique, is based on the insertion of a retroviral- or plasmid-based vector into a gene, resulting in a loss-of-function mutation, while simultaneously reporting its expression pattern and providing a molecular tag to facilitate cloning. The discovery of vertebrate DNA transposons in the mouse and recent improvements has also led to their increased use in insertional mutagenesis screens. Several public resources have been set-up recently by the academic community to distribute information and materials generated from these large-scale screens. These new resources should accelerate the study and understanding of biological and developmental processes.
