Mutation
description
Allele Type:    Targeted (Conditional ready, Humanized sequence, Inserted expressed sequence, No functional change)
Mutations:    Insertion, Intragenic deletion
 
Ctnnb1tm2(Nfkbia)Rsu expresses 1 gene
 
Mutation detailsThis allele is similar to Catnnb1tm1(Nfkbia)Rsu in that an Nfkbia cDNA encoding amino acids 71 through 317 was inserted at the start codon of Catnnb1, but in this case, a floxed stop cassette preceded the Nfkbia sequence, precluding its expression. As in Catnnb1tm1(Nfkbia)Rsu, the coding region of the first coding exon and the following 4 downstream exons were deleted. (J:71744)
