摘要

A systematic screen termed the allelic mes- sage display (AMD) was developed for the hunting of im- printed genes. In AMD, differential display PCR is adopted to image allelic expression status of multiple polymorphic tran- scripts in two parental mouse strains, reciprocal F1 hybrids and pooled backcross progenies. From the displayed patterns, paternally and maternally expressed transcripts can be un- equivocally identified. The effectiveness of AMD screening was clearly demonstrated by the identification of a paternally expressed gene Impact on mouse chromosome 18, the pre- dicted product of which belongs to the YCR59c/yigZ hypo- thetical protein family composed of yeast and bacterial pro- teins with currently unknown function.
