An object of the present invention is to solve problems in terms of stagnation of research on norovirus by providing a cultured transgenic cell or a transgenic animal in which murine norovirus (MNV) can be grown across the barrier of host specificity in mammalian cells, and providing a screening method that uses the cultured transgenic cell or the transgenic animal. The present inventors have found that MNV infection is determined in a cultured transgenic mammalian cell or a mammal possessing the cultured transgenic mammalian cell as its own cell, the cultured transgenic mammalian cell containing one or more species selected from the entirety or a portion of the murine CD300F gene and/or a CD300 family gene having an extracellular domain nucleotide sequence similar to that of the murine CD300F gene. The present inventors have solved the aforementioned problems by providing, for example, a norovirus-related drug screening method on the basis of this finding.
