| 摘要 |
The invention features transgenic non-human mammals and transgenic cells expressing a radical fringe transgene comprising a radical fringe coding sequence, wherein expression of said coding sequence in said mammal is driven by an operably linked regulatory sequence that directs inducible and keratinocyte-specific expression, and wherein said mammal exhibits accelerated wound healing and/or increased keratinocyte proliferation following the induction of transgene expression. The invention also features polynucleotide and amino acid sequences for human radical fringe, methods of treating psoriasis and promoting wound healing by administering a modulator of radical fringe polypeptide activity, and methods of identifying modulators of radical fringe activity.
