摘要: The transcription factor and tumour suppressor p53 its two homologues p63 p73 form a family of proteins. show much greater molecular complexity than because they are expressed both as multiple alternatively spliced C-terminal isoforms, N-terminally deleted, dominant-negative proteins that reciprocal functional regulation. In addition, several other factors, such post-translational modifications specific common regulatory proteins, result overall in subtle modulation their biological effects. Although all p53, members regulators the cell cycle apoptosis, developmental abnormalities p73- p63-null mice do not enhanced susceptibility knockouts, suggesting complex processes modulate effects this
