p63 Antibody

Tumor protein p63 (TP63), also known as TP73L is a protein that in humans is encoded by the TP63 gene. It is a member of the p53 family of transcription factors. This gene encodes for two main isoforms by alternative promoters (TAp63 and dNp63). TP63 has been mostly restricted to its apoptotic function and more recently as the guardian of oocyte integrity. It has been found that the combined loss of TP63 and p73 results in the failure of cells containing functional p53 to undergo apoptosis in response to DNA damage. It is an essential regulator of stem cell maintenance in stratified epithelial tissues. TP63 is also critical for maintaining the progenitor-cell populations that are necessary to sustain epithelial development and morphogenesis.
