Nkx2.2{LCA} mouse ESC line A mouse ESC line in which the targeted gene, NK2 transcription factor related, locus 2 (NCBI Gene ID: 18088), has been modified (allele type: Cassette Acceptor) to targeted mutation 1 (MGI ID: Nkx2.2{tm1(LCA)}). This ES cell line contains a loxed cassette acceptor (LCA) allele that may be utilized for the exchange of DNAs of interest into the Nkx2.2 locus by recombinase mediated cassette exchange (RMCE). This LCA uses a Lox71/66 and Lox2272 strategy for RMCE and allows for manipulation of a 5.1 kb region of the gene (contains promoter, exon 1, and exon 2). This leads to a variety of experiments that can be performed using a wide range of cassette designs. Person: Mark A.
