Targeted Allele Detail
Symbol: Cntn2tm1Furl
Name: contactin 2; targeted mutation 1, Andrew Furley
MGI ID: MGI:2677610
Synonyms: Cntn2tm1Pele, TAG-1-, TAG1-tau-lacZ
Gene: Cntn2  Location: Chr1:132509425-132543251 bp, - strand  Genetic Position: Chr1, 57.42 cM
Germline Transmission:  Earliest citation of germline transmission: J:85502
Parent Cell Line:  W9.5/W95 (ES Cell)
Strain of Origin:  129S1/Sv-Oca2+ Tyr+ Kitl+
Allele Type:    Targeted (Null/knockout, Reporter)
Mutations:    Insertion, Intragenic deletion
Mutation detailsExons 2 through 5 were replaced with a cassette containing tau-lacZ and neo. The deleted region included the start codon, and sequence encoding the signal peptide and first two Ig domains. Neither transcript nor protein was detected by RT-PCR and Western blot analysis of homozygous mutant mice. Immunolabeling of sciatic nerve tissue showed no specific staining. (J:85502)
