Targeted Allele Detail
Symbol: Smad1tm2.1Rob
Name: SMAD family member 1; targeted mutation 2.1, Elizabeth J Robertson
MGI ID: MGI:2155485
Synonyms: Smad1Robcn
Gene: Smad1  Location: Chr8:79338395-79399518 bp, - strand  Genetic Position: Chr8, 37.56 cM
Germline Transmission:  Earliest citation of germline transmission: J:71998
Parent Cell Line:  CCE/EK.CCE (ES Cell)
Strain of Origin:  129S/SvEv-Gpi1c
Allele Type:    Targeted (Null/knockout)
Mutation:    Intragenic deletion
Mutation detailsThis allele was generated by crossing mice carrying the Smad1tm2Rob allele to mice carrying a Cre transgene controlled by a mouse protamine 1 promoter that directs Cre-recombinase expression specifically to the male germline. An in vivo Cre-mediated excision removed all of the first coding exon and approximately 2kb of 5' and 3' flanking genomic sequences, and left a single loxP and EcoRI site in the locus. Northern analysis of 9.5dpc homozygous embryos using a probe for the 3' UTR detected a shorter transcript, but not the wild-type transcript. Western blot analysis using an antibody that recognizes the MH2 domain did not detect intact or truncated protein in 9.5dpc homozygous embryos. (J:71998)
Inheritance:    Recessive
