Symbol: Lig4tm2.1Fwa
Name: ligase IV, DNA, ATP-dependent; targeted mutation 2.1, Frederick W Alt
MGI ID: MGI:4437270
Synonyms: Lig4R
Gene: Lig4  Location: Chr8:10020020-10027680 bp, - strand  Genetic Position: Chr8, 4.52 cM
Germline Transmission:  Earliest citation of germline transmission: J:157574
Parent Cell Line:  TC1/TC-1 (ES Cell)
Strain of Origin:  129S6/SvEvTac
Allele Type:    Targeted (Humanized sequence)
Mutations:    Insertion, Nucleotide substitutions
Mutation detailsA targeting vector, containing the R278H (CGC to CAT) substitution and a floxed neomycin resistance (NeoR) gene, was inserted into the locus. The neo was subsequently removed via cre-mediated recombination. Western-blot analysis, performed on total lysate of thymocytes, showed that the mutant protein was expressed at slightly reduced levels as compared to wild-type. (J:157574)
