Targeted Allele Detail
Symbol: Smpd1tm1Wst
Name: sphingomyelin phosphodiesterase 1, acid lysosomal; targeted mutation 1, Wilhelm Stoffel
MGI ID: MGI:2183207
Synonyms: ASM-, asmase-
Gene: Smpd1  Location: Chr7:105554360-105558389 bp, + strand  Genetic Position: Chr7, 55.9 cM
Germline Transmission:  Earliest citation of germline transmission: J:26748
Parent Cell Line:  E14 (ES Cell)
Strain of Origin:  129P2/OlaHsd
Allele Type:    Targeted (Null/knockout)
Mutation:    Insertion
Mutation detailsThe gene was disrupted at codon 370 by insertion of a neomycin resistance cassette into exon 3 via homologous recombination. Absence of gene expression in homozygous mutant animals was demonstrated by Northern blot analysis of liver, spleen, and brain tissues using the full cDNA sequence as a probe. No enzyme activity was detectable in total protein extracts of liver, spleen, and brain from homozygous mutants. (J:26748)
