The ATF1 (Phospho-Ser63) antibody is designed to detect the activated form of Activating Transcription Factor 1 (ATF1) when phosphorylated at serine residue 63. ATF1. a member of the CREB/ATF family of basic leucine zipper (bZIP) transcription factors, plays a critical role in regulating gene expression in response to cellular stress, hormonal signals, and growth factors. Phosphorylation at Ser63. mediated by kinases such as protein kinase A (PKA) or mitogen- and stress-activated kinase 1 (MSK1), enhances ATF1's transcriptional activity by promoting its interaction with coactivators like CREB-binding protein (CBP). This post-translational modification is often triggered by cAMP signaling, UV radiation, or mitogenic stimuli, linking ATF1 to processes like cell survival, proliferation, and adaptation to stress.
The ATF1 (Phospho-Ser63) antibody is widely used in research to study ATF1 activation dynamics in pathways involving cAMP, MAPK, or p38 signaling. It is applied in techniques such as Western blotting, immunofluorescence, and immunohistochemistry to assess phosphorylation status in cell lines, tissues, or experimental models. Dysregulation of ATF1 activity, including aberrant phosphorylation, has been implicated in cancers, neurodegenerative disorders, and immune responses. By specifically recognizing the phosphorylated form, this antibody helps elucidate ATF1's role in disease mechanisms and its crosstalk with other signaling networks. Proper controls, including non-phosphorylated ATF1 detection, are recommended to ensure specificity in experimental settings.
