Description

ATF2 (Activating Transcription Factor 2) serves as a critical mediator of cellular stress responses and gene regulation, functioning both as a sequence-specific DNA-binding transcription factor and as a histone acetyltransferase. This dual functionality positions ATF2 at the intersection of signal transduction and chromatin remodeling, making it an essential target for researchers investigating cAMP-dependent signaling pathways, stress-activated kinase cascades, and epigenetic mechanisms of gene control.

This recombinant monoclonal antibody, generated against a synthetic peptide derived from human ATF2, offers the reproducibility and consistency that demanding experimental workflows require. Because the antibody sequence is defined and production occurs in a controlled recombinant system, researchers can expect reliable performance across experiments and between lots—an important consideration for longitudinal studies or when establishing standardized protocols.

Validation testing confirms robust performance in Western blot applications, where the antibody successfully detects ATF2 in both K562 and 293T whole cell lysates at dilutions ranging from 1:500 to 1:5000. The observed band at 70 kDa runs higher than the predicted molecular weight, a shift commonly attributable to post-translational modifications such as phosphorylation or glycosylation that ATF2 undergoes during cellular activation. For tissue-based studies, immunohistochemistry validation in paraffin-embedded human prostate tissue demonstrates clear nuclear staining patterns consistent with ATF2's role as a transcription factor, with optimal results achieved at dilutions between 1:50 and 1:200.

Whether investigating stress response pathways, characterizing transcriptional networks, or exploring epigenetic regulation, this antibody provides researchers with a dependable tool for detecting ATF2 in human samples across multiple experimental platforms.

Target Background

Function

Transcriptional activator which regulates the transcription of various genes, including those involved in anti-apoptosis, cell growth, and DNA damage response. Dependent on its binding partner, binds to CRE (cAMP response element) consensus sequences (5'-TGACGTCA-3') or to AP-1 (activator protein 1) consensus sequences (5'-TGACTCA-3'). In the nucleus, contributes to global transcription and the DNA damage response, in addition to specific transcriptional activities that are related to cell development, proliferation and death. In the cytoplasm, interacts with and perturbs HK1- and VDAC1-containing complexes at the mitochondrial outer membrane, thereby impairing mitochondrial membrane potential, inducing mitochondrial leakage and promoting cell death. The phosphorylated form (mediated by ATM) plays a role in the DNA damage response and is involved in the ionizing radiation (IR)-induced S phase checkpoint control and in the recruitment of the MRN complex into the IR-induced foci (IRIF). Exhibits histone acetyltransferase (HAT) activity which specifically acetylates histones H2B and H4 in vitro. In concert with CUL3 and RBX1, promotes the degradation of KAT5 thereby attenuating its ability to acetylate and activate ATM. Can elicit oncogenic or tumor suppressor activities depending on the tissue or cell type.

Subcellular Location

Nucleus. Cytoplasm. Mitochondrion outer membrane. Note=Shuttles between the cytoplasm and the nucleus and heterodimerization with JUN is essential for the nuclear localization. Localization to the cytoplasm is observed under conditions of cellular stress and in disease states. Localizes at the mitochondrial outer membrane in response to genotoxic stress. Phosphorylation at Thr-52 is required for its nuclear localization and negatively regulates its mitochondrial localization. Co-localizes with the MRN complex in the IR-induced foci (IRIF).
