International strain name | 129(Cg)-Tectatm4.1Gpr/GprH |
Alternative name | Tecta |

Information from provider
Provider | Guy Richardson |
Provider affiliation | School of Life Sciences, University of Sussex |
Genetic information | Exon 17 was replaced with one in which two point mutations (C>T and G>A) results in the amino acid substitutions of phenylalanine for leucine at position 1820 (L1820F) and aspartic acid for glycine at position 1824 (G1824D). Cre-mediated recombination was used to remove the neomycin resistance cassette after correct targeting was confirmed. |
Phenotypic information | Homozygous:In Tecta |
Breeding history | F1 mice from germline transmitting chimera were mated with a Cre deleter line to remove the floxed neomycin resistance cassette and the F2 generation then outbred to 129SvEv. |

Homozygous fertile | yes |
