Mutation
description
Allele Type:    Targeted (Modified regulatory region, Null/knockout)
Mutations:    Insertion, Intragenic deletion
 
Mutation detailsA loxP-flanked neomycin resistance cassette replaced the 1.2kb region of the promoter, corresponding to a cis-acting silencer element. This cassette was then excised in ES cells by cre-mediated recombination, resulting in the deletion of the silencer element. (J:63213)
Inheritance:    Dominant
