Targeted Allele Detail
Symbol: B4galt1tm1Yiw
Name: UDP-Gal:betaGlcNAc beta 1,4- galactosyltransferase, polypeptide 1; targeted mutation 1, Yoichiro Iwakura
MGI ID: MGI:2450889
Synonyms: Beta4GalT-I-, GalT-
Gene: B4galt1  Location: Chr4:40804602-40854005 bp, - strand  Genetic Position: Chr4, 20.46 cM
Germline Transmission:  Earliest citation of germline transmission: J:40026
Parent Cell Line:  R1 (ES Cell)
Strain of Origin:  (129X1/SvJ x 129S1/Sv)F1-Kitl+
Allele Type:    Targeted (Null/knockout)
Mutations:    Insertion, Intragenic deletion
Mutation detailsExon 1 was replaced with a PGK-neo cassette inserted by homologous recombination. The deleted exon contained the start codon and encoded the golgi retention signal. While the targeting vector was designed to disrupt both long and short isoforms, assays showed residual endogenous activity (less than 5% of wild-type levels) in homozygous mutant mice. (J:40026)
