Background

The E1A-binding protein p300 is a histone acetyltransferase that also acts to acetylate other proteins, such as p53. p300 acts as a transcriptional coactivator that can serve as an adaptor molecule to bridge to transcriptional regulators. In addition, p300 binds to PCNA and may participate in chromatin remodeling.

Limitations

This product is for research use only and is not approved for use in humans or in clinical diagnosis. Primary Antibodies are guaranteed for 1 year from date of receipt.
