What is the AP-1 gene?
What is the AP-1 gene? Activator protein 1 (AP-1) is a transcription factor that regulates gene expression in response to a variety of stimuli, including cytokines, growth factors, stress, and bacterial and viral infections. AP-1 controls a number of cellular processes including differentiation, proliferation, and apoptosis. What proteins activate genes? Activation of a gene — transcription — is kicked off when proteins called transcription factors bind to two key bits of DNA, an enhancer and a promoter. How does an activator protein work? Most activators function by binding sequence-specifically to a regulatory DNA site located near a promoter and making...
