Mutation origin

• Germline Transmission: Earliest citation of germline transmission: J:120916
• Parent Cell Line: AK7 (ES Cell)
• Strain of Origin: 129S4/SvJaeSor

Mutation description

• Allele Type: Targeted (Null/knockout)
• Mutations: Insertion, Intragenic deletion
• Mutation details: The sigma 1-specific targeting vector was designed to replace exon 1 and part of exon 2 with a neomycin resistance cassette in reverse orientation. Immunoblot confirmed the absence of the sigma 1 isoform, and the normal expression of the sigma 6 isoform. (J:120916)
