| molecularNote | The coding sequence was replaced with a floxed neomycin resistnace cassette and a modified coding sequence in which a C to T point mutation results in the amino acid substitution of valine for alanine at position 159 (A159V). This mutation has been observed in human cancers. Cre-mediated recombination removed the selection cassette. |
