Biological process

positive regulation of p53 induced by DNA damage response, up regulation of DNA damage response, signal transduction by p53 class mediator, up-regulation of DNA damage response, signal transduction by p53 class mediator, upregulation of DNA damage response, signal transduction by p53 class mediator

Any process that activates, maintains or increases the rate of the cascade of processes induced by the cell cycle regulator phosphoprotein p53, or an equivalent protein, in response to the detection of DNA damage.
