The p300-CBP coactivator family in humans is composed of two closely related transcriptional co-activating proteins (or coactivators):

  1. p300 (also called EP300 or E1A binding protein p300)
  2. CBP (also known as CREB-binding protein or CREBBP)

Both p300 and CBP interact with numerous transcription factors and act to increase the expression of their target genes.[2][3]
