Targeted Allele Detail
Symbol: Fn1tm4Hyn
Name: fibronectin 1; targeted mutation 4, Richard Hynes
MGI ID: MGI:3764511
Synonyms: EIIIA-EIIIB-, EIIIA/EIIIB-double-null
Gene: Fn1  Location: Chr1:71585520-71653200 bp, - strand  Genetic Position: Chr1, 36.05 cM, cytoband C1-C5
Germline Transmission:  Earliest citation of germline transmission: J:126737
Parent Cell Line:  Other (see notes) (ES Cell)
Strain of Origin:  129P2/OlaHsd
Allele Type:    Targeted (Null/knockout)
Mutation:    Intragenic deletion
Mutation detailsES cells from homozygous Fn1tm1Ksek male mouse in which exon EDB (EIIIB) was deleted and replaced with a singe loxp site was isolated and targeted with the same construct used in Fn1tm1Bwg. Following homologous recombination and transient cre-mediated recombination, a single loxp site was left in place of the exon encoding the EIIIA domain. Northern and Western blot confirmed the absence of EIII1 and EIIIB mRNA and protein and that deletion of both of those exons did not compromise the expression of FN mRNA and protein, nor the deposition of FN into the matrix.
