In response to our recent report on the Brdm2 mouse model for p63 function, 1 Mikkola et al. 2 raise concerns on three of our statements:(1) they maintain their initial claim that no functional p63 protein of any kind is synthesized in mice homozygous for the Brdm2 allele;(2) they report the occurrence of spontaneous wild-type allelic reversions in these mice, leading to patches of completely normal epidermis, and propose that these normal reverted skin patches are in fact the multilayered epithelia we described; and (3) they insist that the Brdm2 allele is phenotypically indistinguishable from a global p63 knockout. We started working with Brdm2 mice (which we received from A Mills about 3 years ago) as a source of p63 KO mice. Extensive molecular and protein analysis of 26 different p63 Brdm2/Brdm2 embryos from multiple generations and multiple litters ranging from day E13 to P1 consistently revealed expression of aberrant truncated p63 variants, not confined to random epidermal patches but widespread, and associated with a transient phenotype consistent with residual functions of the targeted allele, as detailed below. We further showed that, in reporter assays, this Brdm2-derived p63 can both activate (as TAp63) and repress (as ANp63) a p53-responsive promoter. We therefore cannot help but maintain the notion that Brdm2 represents a functional aberrant hypomorphic allele but not a null allele.
