Spontaneous Allele Detail
Symbol: Casp4del
Name: caspase 4, apoptosis-related cysteine peptidase; deletion
MGI ID: MGI:5473345
Synonyms: Casp129
Gene: Casp4  Location: Chr9:5308828-5336783 bp, + strand  Genetic Position: Chr9, 2.46 cM, cytoband A1
Strain of Origin:  129P3/J and 129S1/SvImJ and 129S2/SvPas and 129S6/SvEvTac and 129X1/SvJ
Allele Type:    Spontaneous (Null/knockout)
Mutation:    Intragenic deletion
Mutation detailsRT-PCR confirmed that five 129 substrains (129X1/SvJ, 129S1/SvImJ, 129S2/SvPas, 129S6/SvEvTac and 129P3/J) express a transcript that lacks exon 7 (delta110 isoform). Sequencing identified a 5 bp deletion in exon 7 that results in the fusion of exon 6 and 8, a frame-shift after proline 304 and a stop codon after 5 aberrant amino acids. This deletion is not present in C57BL/6. Western blot analysis confirmed the absence of protein expression in LPS-primed macrophage. (J:193522)
