Abstract
The analysis of rare NMDAR gene variants in mice, coupled with a fundamental understanding of NMDAR function, plays a crucial role in achieving therapeutic success when addressing NMDAR dysfunctions in human patients. For the generation of such NMDAR mouse models, a basic knowledge of receptor structure, along with skills in database sequence analysis, cloning in E. coli, genetic manipulation of embryonic stem (ES) cells, and ultimately the genetic modification of mouse embryos, is essential. Primarily, this chapter will focus on the design and synthesis of NMDAR gene-targeting vectors that can be used successfully for the genetic manipulation of mice. We will outline the core principles of the design and synthesis of a gene targeting vector that facilitates the introduction of single-point mutations in NMDAR-encoding genes in mice. The transformation of ES cells, selection of positive ES cell colonies, manipulation of mouse embryos, and genotyping strategies will be described briefly.
