표적 설명

CREB-binding protein (UniProt: Q92793; also known as EC: 2.3.1.48, Histone lysine acetyltransferase CREBBP, Protein-lysine acetyltransferase CREBBP) is encoded by the CREBBP (also known as CBP) gene (Gene ID: 1387) in human. CBP, a homolog of p300, serves as a transcriptional co-activator of various sequence-specific transcription factors that are involved in a wide array of cellular activities, such as DNA repair, cell growth, differentiation, and apoptosis. It possesses intrinsic acetyltransferase activity by which it acetylates histones, giving specific tag for transcription activation. It can also acetylate non-histone proteins, such as DExD-box helicase 21, interferon regulatory factor 2, and nuclear receptor coactivator 3. CBP facilitates the transcription of active genes by acting as adapter protein bridging DNA binding transcription factors to the basal transcription machinery and by loosening chromatin through histone tail acetylation. It binds specifically to phosphorylated CREB and enhances its transcriptional activity toward cAMP-responsive genes. CBP and p300 share overall 63% amino acid sequence identity and about 90% homology in their histone acetyltransferase domain (aa 1323-1700). Structurally, CBP contains several domains: a receptor-interacting domain (RID); KIX binding site of CREB; a bromo domain (aa 1103-1175); three cysteine and histidine-rich domains, a glutamine-and proline-rich domain (QP), and a steroid receptor co-activator-1 interaction domain (SID). Methylation of the KIX domain by coactivator associated arginine methyltransferase 1 (CARM1) blocks its association with CREB that results in the blockage of CREB signaling. Phosphorylation of CBP by IKK- at serine 1382 and 1386 promotes cell growth by switching the binding preference of CBP from TP53 to NF-kB. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

물리적 형태

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.

재구성

0.3 mg/mL after reconstitution at 25 µL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

저장 및 안정성

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 µL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
