description
Allele Type:    Targeted (Null/knockout)
Mutations:    Insertion, Intragenic deletion
 
Mutation detailsA 1.8kb genomic fragment containing exon 3 was replaced by an HPRT minigene. These sequences encode three of the four transmembrane domains, the amphipathic helix domain and the four cysteines essential for ligand binding. No transcript produced from this allele was detectable by northern blotting. (J:54994)
