Target data

Function

This protein binds the cAMP response element (CRE) (consensus: 5'-GTGACGT[AC][AG]-3'), a sequence present in many viral and cellular promoters. Binds to the Tax-responsive element (TRE) of HTLV-I. Mediates PKA-induced stimulation of CRE-reporter genes. Represses the expression of FTH1 and other antioxidant detoxification genes. Triggers cell proliferation and transformation.

Production method for this product has been changed from hybridoma to recombinant on 15th August 2024

Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.

Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. The carrier-free buffer and high concentration allow for increased conjugation efficiency.

This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.

Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with 1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.

This product is compatible with the Maxpar® Antibody Labeling Kit from Fluidigm, without the need for antibody preparation. Maxpar® is a trademark of Fluidigm Canada Inc.

This product is a recombinant monoclonal antibody, which offers several advantages including:

  • - High batch-to-batch consistency and reproducibility
  • - Improved sensitivity and specificity
  • - Long-term security of supply
  • - Animal-free batch production

Activity summary

'ATF1' also known as activating transcription factor 1 is a protein with a mass of approximately 29 kDa. This protein belongs to the ATF/CREB family of transcription factors and functions as a DNA-binding protein. It plays an important role in regulating gene expression by binding to cAMP response elements (CRE) in the promoter regions of target genes. ATF1 is widely expressed in multiple tissues including the brain and various endocrine organs functioning as an important regulator of cellular responses to environmental stimuli.

Biological function summary

ATF1 participates in the regulation of various cellular processes including proliferation differentiation and response to stress signals. It can form heterodimers with other members of the CREB family such as CREB1 allowing it to regulate diverse gene sets. These complexes enhance the DNA-binding affinity and transcriptional activity directed by CRE sites influencing cellular homeostasis and adaptation. Additionally post-translational modifications such as phosphorylation by protein kinases modulate ATF1 activity and stability.

Pathways

ATF1 integrates into the cAMP signaling pathway and the MAPK/ERK pathway. In the cAMP signaling pathway ATF1 responds to hormonal signals that activate adenylate cyclase resulting in increased levels of cAMP and subsequent activation of Protein Kinase A (PKA). PKA phosphorylates ATF1 increasing its transcriptional activity. In the MAPK/ERK pathway ATF1 links to the activation of mitogen-activated protein kinases which modulate gene expression related to cell growth and survival. This interaction also involves other proteins such as CREB and ATF2 highlighting a network of transcription factors that co-regulate gene expression.

Associated diseases and disorders

ATF1 has implications in cancer and neurodegenerative diseases. In cancer alterations in ATF1 expression or function can lead to aberrant cell growth and survival often linked to its cooperation with CREB-related proteins. Specifically chromosomal translocations involving ATF1 have been observed in certain sarcomas like clear cell sarcoma where it forms a fusion protein that acts as a potent transcriptional activator. Concerning neurodegenerative diseases ATF1 may play a role in neuronal survival and stress response with its activity being impacted by dysregulated signaling pathways and interacting proteins such as CREB and ATF2 contributing to disease progression.
