Target description

Cyclic AMP-dependent transcription factor ATF-3 (UniProt: P18847; also known as cAMP-dependent transcription factor ATF-3, Activating transcription factor 3) is encoded by the ATF3 gene (Gene ID: 467) in human. ATF3 is a member of the ATF/cAMP response element-binding (CREB) family that binds to the cAMP response element (CRE) (consensus: 5′-GTGACGT[AC][AG]-3′). It serves as a stress-induced transcription factor that plays a role in modulating metabolism, immunity, and oncogenesis. It acts as a hub of the cellular adaptive-response network. Multiple extracellular signals, including ER stress, cytokines, chemokines, and lipopolysaccharides can induce ATF3. It acts as a transcriptional repressor by forming a homodimer. It may repress transcription by stabilizing the binding of inhibitory cofactors at the promoter. ATF3 can also interact with proteins via its basic leucine zipper (bZIP; aa 86-149) domain and modulate cellular functions independently of its transcriptional activity. ATF3 is also involved in glucose metabolism in a variety of organs and tissues, including the pancreas, liver, adipose tissue, hypothalamus, and heart. Overexpression of ATF3 in the liver is shown to reduce the levels of gluconeogenic enzymes, including phosphoenolpyruvate carboxykinase (PEPCK) and fructose-1,6-bisphosphatase (FBP). Its expression is up-regulated by low glucose and down-regulated by high glucose levels. Lower levels of ATF3 are observed in hepatocellular carcinoma (HCC) and are associated with clinical cancer stage and pathological tumor grade in patients with HCC. Its low expression is associated with poor overall survival. Five isoforms of ATF3 have been described that are produced by alternative splicing. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form

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.

Reconstitution

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.

Storage and Stability

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.
