Mutation origin

• Germline Transmission: Earliest citation of germline transmission: J:86257
• Parent Cell Line: R1 (ES Cell)
• Strain of Origin: (129X1/SvJ x 129S1/Sv)F1-Kitl⁺

Mutation description

• Allele Type: Targeted (Null/knockout)
• Mutations: Insertion, Intragenic deletion
• Mutation details: 0.3 kb of the first coding exon was replaced with a neomycin selection cassette inserted by homologous recombination. Transcript containing the neo cassette was detected by RT-PCR analysis of mutant mice. Mutant protein potentially encoded by the detected transcript lacks the catalytic unit and is putatively nonfunctional. Inositol 1,4,5-triphosphate 3-kinase activity was attenuated in a dose dependent manner in mutant mice. (J:86257)
