Mutation
description
Allele Type:    Targeted (Null/knockout)
Mutations:    Insertion, Intragenic deletion
 
Mutation detailsMost of exon 2 and all of exon 3 which together encode for the leader sequence, the first IgV domain and the ICOS-binding site were replaced with a neomycin-resistance gene. Loss of protein expression in mice homozygous for this deletion was established by flow cytometric analysis of spleen cells. (J:84668)
