Mutation description

• Allele Type: Targeted (Not Applicable)
• Mutation: Single point mutation
• Mutation details: Exon 5 was engineered with a C to T mutation that altered the sequence to change codon 215 from one encoding glutamine to a premature stop codon (p.Q215*). A floxed neomycin selection cassette was also inserted downstream of exon 5 and subsequently removed via cre-mediated recombination. Western blot confirmed the production of a smaller truncated protein zero lacking 33 amino acids of the C-terminal intracellular domain and with a molecular weight of approximately 24 kDa that is expressed at low levels. This truncated protein shows altered trafficking to non-myelin plasma membranes. (J:171510, J:267903)
