| molecularNote | A floxed neo cassette was inserted upstream of exon 5 and a T to G mutation, resulting in a cysteine to glycine substitution at amino acid position 61 (C61G) in a conserved RING domain, was introduced via homologous recombination. Cre mediated recombination removed the neo cassette. |
