Colon cancer stem cell over-expressing TAp63α

p63, a member of p53 family, is transcribed in different variants, containing (TA) or lacking (N) the N-terminal transactivation domain. Although the proteins of p53 family share high sequence and structural similarities, distinct functions for p63 are emerging. Here we provided a quantitative proteomic analysis by stable isotope dimethyl labeling of colon cancer stem cells over-expressing TAp63α in order to investigate the cellular pathways modulated by this p63 isoform.
