General description
Monoclonal Anti-p300/CBP (mouse IgG1 isotype) is derived from the NM11 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with a native human p300. The KAT2B (lysine acetyltransferase 2B) gene encodes a p300/CBP (CREB binding protein)-associated factor, which belongs to the family of GNAT (GCN5 (general control nonderepressible 5)-related N-acetyltransferase).
Specificity
Reacts specifically with both p300 and CBP but not with the related p270 molecule. The epitope recognized by the antibody resides within the 21 amino acid stretch spanning amino acids 2071-2091 near the CBP C-terminus. CBP and p300 differ by three noncontiguous residues within this 21 amino acid region, a difference that does not detectably affect the reactivity of the antibody.
Immunogen
native human p300.
Biochem/physiol Actions
p300/CBP are capable of binding to a variety of transcriptional activator and regulatory molecules, including p53 and nuclear hormone receptors. The complexity of these p300/CBP cellular associations suggests that both proteins play a central role in the coordination of gene expression during cell growth and differentiation.
KAT2B (lysine acetyltransferase 2B) possess histone acetyltransferase (HAT) activity and is thus known to regulate transcription process. Acetylation also influences the chromatin structure. Lysine acetylation significantly contributes to protein modification. It is essential for establishing protein function by altering its structure, activity and molecular interaction.
Physical form
