Active Recombinant Human CREBBP, GST-tagged

• Cat.No.: CREBBP-192H
• Product Overview: Recombinant human KAT3A (CREBBP) (1319-1710) was expressed by baculovirus in Sf9 insect cells using an N-terminal GST tag.

Specification

• Species: Human
• Source: Sf9 Cells
• Tag: GST
• Protein Length: 1319-1710 a.a.
• Description: KAT3A has intrinsic histone acetyltransferase activity that acts as a scaffold to stabilize additional protein interactions with the transcription complex and acetylates both histone and non-histone proteins. KAT3A (CREBBP) expressed as a nuclear protein that binds to cAMP-response element binding protein (CREB) and involved in the transcriptional coactivation of many different transcription factors. KAT3A plays a main role in embryonic development, growth control, and homeostasis by coupling chromatin remodeling to transcription factor recognition. KAT3A also plays a critical role in the transmission of inductive signals from cell surface receptors to the transcriptional apparatus.
• Form: Recombinant protein stored in 50mM Tris-HCl, pH 7.5, 50mM NaCl, 10mM glutathione, 0.1mM EDTA, 0.25mM DTT, 0.1mM PMSF, 25% glycerol.
• Bio-activity: The specific activity of KAT3A (CREBBP) was determined to be 32 nmol /min/mg
• Molecular Mass: ~72 kDa
• Purity: >90% by densitometry
• Applications: Acetyltransferase Assay
• Storage: Store product at –70 centigrade. For optimal storage, aliquot target into smaller quantities after centrifugation and store at recommended temperature. For most favorable performance, avoid repeated handling and multiple freeze/thaw cycles.
