Mutation origin

• Germline Transmission: Earliest citation of germline transmission: J:85950
• Parent Cell Line: E14 (ES Cell)
• Strain of Origin: 129P2/OlaHsd

Mutation description

• Allele Type: Targeted (Dominant negative, Null/knockout)
• Mutation: Nucleotide substitutions
• Mutation details: Acetyltransferase (AT) activity was ablated via the incorporation of engineered point mutations at the endogenous locus. The mutations substitute alanine and serine for tryptophan and tyrosine (WY(1466-1477)AS). A single loxP site remained in the intron following the missense mutations after the excision of floxed neo cassette used for selection. Western blot analysis indicated mutant protein was expressed at wild-type levels. (J:85950)
• Inheritance: Dominant
