Mutation origin

• Germline Transmission: Earliest citation of germline transmission: J:55865
• Parent Cell Line: Not Specified (ES Cell)
• Strain of Origin: 129/Sv

Mutation description

• Allele Type: Targeted (Null/knockout)
• Mutations: Insertion, Intragenic deletion
• Mutation details: A neomycin resistance cassette replaced a genomic fragment containing exon A3. This exon encodes sequences common to both isoforms of the protein. Removal of this exon is predicted to cause a frameshift mutation and result in premature termination of the protein. Immunohistochemistry analysis on skin derived from homozygous mice confirmed that the protein was not detectable. (J:55865)
