Targeted Allele Detail
Symbol: Egr1tm1Pch
Name: early growth response 1; targeted mutation 1, Patrick Charnay
MGI ID: MGI:2181755
Synonyms: Egr-1-LacZ), Krox-24-, Zif268-
Gene: Egr1  Location: Chr18:34861207-34864956 bp, + strand  Genetic Position: Chr18, 18.76 cM, cytoband C/D
Germline Transmission:  Earliest citation of germline transmission: J:45064
Parent Cell Line:  CK35 (ES Cell)
Strain of Origin:  129S2/SvPas
Allele Type:    Targeted (Null/knockout, Reporter)
Mutation:    Insertion
Mutation detailsA construct containing a promoterless lacZ gene adjoined to a neomycin selection gene was inserted 50 bp upstream of the translational start codon. The insertion introduced a frameshift mutation upstream of the DNA-binding domain. An absence of encoded mRNA and protein was determined by in situ hybridization and immunocytochemical analyses of homozygous mutant mice. (J:45064)
