abstract：:p300 acetylates and activates the tumor suppressor p53 after DNA damage. Here, we show that MDM2, a negative-feedback regulator of p53, inhibited p300-mediated p53 acetylation by complexing with these two proteins. First, we purified a p300-MDM2-p53 protein complex from HeLa nuclear extracts, which was inactive in p53...

However, there is no topographic representation of acoustic space, and individual auditory cortical neurons are often broadly tuned to stimulus location.
