Symbol:	Otx2tm9Asim
Name:	orthodenticle homeobox 2; targeted mutation 9, Antonio Simeone
MGI ID:	MGI:4365828
Synonyms:	Otx2delta3SS
Gene:	Otx2  Location: Chr14:48894238-48905101 bp, - strand  Genetic Position: Chr14, 25.36 cM
Alliance:	Otx2tm9Asim page

Germline Transmission:	Earliest citation of germline transmission: J:153562
Parent Cell Line:	E14TG2a.4 (ES Cell)
Strain of Origin:	129P2/OlaHsd

Allele Type:    Targeted Mutations:    Insertion, Nucleotide substitutions   Mutation details: The major and two cryptic splice sites upstream from the translation initiation codon were mutagenized and a floxed neo cassette was inserted into the downstream intron. The absence of protein expression of isoforms A and B was confirmed by western blot analysis. Expression of isoforms C and D are normal. (J:153562)
