Mutation origin

• Germline Transmission: Earliest citation of germline transmission: J:80520
• Parent Cell Line: CT129 (ES Cell)
• Strain of Origin: 129S/Sv

Mutation description

• Allele Type: Chemically induced (ENU) (Dominant negative)
• Mutation: Single point mutation
• Mutation details: A transition mutation (G to A) in the splice donor site of intron 10 resulted in an aberrant transcript lacking exon 10. Furthermore, codons 436 through 455 in the Mad homology 2 domain, were shifted out of frame. Analysis of protein levels showed reductions greater than 50% in heterozygous ES cells as well as in primary embryonic fibroblasts, indicating a dominant negative property. No truncated protein was detected in primary embryonic fibroblasts. (J:80520)
