Mutation origin

• Germline Transmission: Earliest citation of germline transmission: J:72426
• Parent Cell Line: W9.5/W95 (ES Cell)
• Strain of Origin: 129S1/Sv-Oca2⁺ Tyr⁺ Kitl⁺

Mutation description

• Allele Type: Targeted (Null/knockout, Reporter)
• Mutations: Insertion, Intragenic deletion
• Mutation details: Exons 2-4 were replaced with a GFP-neo cassette via homologous recombination. The gene targeting event deletes the first 440 amino acids of the protein, which encodes the entire signal sequence and most of the extracellular Sema-like domain. Absence of gene expression in homozygous mutants was confirmed by RT-PCR analysis of RNA from E16.5 embryos and by Western analysis of brain lysates from postnatal day 1 homozygous mutant neonates.
