Targeted Allele Detail
Symbol: Ncam1tm1Mag
Name: neural cell adhesion molecule 1; targeted mutation 1, Terry Magnuson
MGI ID: MGI:2182406
Synonyms: Ncam-180-, Ncamtm1Cwr
Gene: Ncam1  Location: Chr9:49502136-49798925 bp, - strand  Genetic Position: Chr9, 26.83 cM
Germline Transmission:  Earliest citation of germline transmission: J:37891
Parent Cell Line:  D3 (ES Cell)
Strain of Origin:  129S2/SvPas
Allele Type:    Targeted (Null/knockout)
Mutations:    Insertion, Intragenic deletion
Mutation detailsA FRT-flanked neomycin resistance cassette driven by beta-actin replaced exon 18, which is specific to the 180 kDa isoform of the protein. Immunoblot analysis of brain tissues from homozygous mutant mice did not detect the 180 kDa isoform in neonatal and adult tissues, and detected the 140kDa isoform in neonatal tissues, but not in adult tissues.
