| molecularNote | A premature stop codon was generated in exon 1 beta, unique to P19ARF, by cre-mediated excision of a floxed neomycin cassette, leaving the cis-regulatory elements of both P19ARF and P16INK4 intact. Loss of P19ARF and presence of P16INK4 was confirmed by western blot analysis of homozygous mutant MEFs. |
