Tcra-J^tm2.2Krg
Targeted Allele Detail

Summary

• Symbol: Tcra-J^tm2.2Krg
• Name: T cell receptor alpha, joining region; targeted mutation 2.2, Michael S Krangel
• MGI ID: MGI:3577334
• Synonyms: DeltaTEAdeltaJ49, Tcra^tm2.1Krg
• Gene: Tcra-J Location: unknown Genetic Position: Chr14, Syntenic

Mutation origin

• Germline Transmission: Earliest citation of germline transmission: J:97736
• Parent Cell Line: EF1 (ES Cell)
• Strain of Origin: 129S/SvEv x C57BL/6

Mutation description

• Allele Type: Targeted (Modified regulatory region, Null/knockout)
• Mutations: Insertion, Intergenic deletion, Intragenic deletion
• Mutation details: Tcra-J^tm2.1Krg ES cells (where the Trja49 promoter (Rr319) and gene segment were replaced with a loxP site flanked neomycin resistance gene cassette and the neo cassette was removed through subsequent cre-mediated recombination) were targeted with a vector replacing the TEA (T early alpha) promoter with a floxed neo cassette, which was removed through subsequent cre-mediated recombination. This allele lacks both the Jalpha49 and TEA promoters. No gross deficiency was found in alphabeta TCR expression or alphabeta T cell development in mutant mice. (J:97736)
