ATF-5, or activating transcription factor 5, is a transcription factor that plays a critical role in regulating gene expression in response to various cellular stressors. It belongs to the ATF/cyclic AMP-responsive element-binding (CREB) protein family and contains a basic leucine zipper (bZIP) domain, which allows it to bind to specific DNA sequences known as cAMP-responsive elements (CREs). ATF-5 is involved in diverse cellular processes, including cell proliferation, differentiation, apoptosis, and stress responses. Under normal physiological conditions, ATF-5 expression is tightly regulated, but its activity can be induced by a variety of stress signals, including oxidative stress, endoplasmic reticulum stress, and DNA damage.
Inhibition of ATF-5 function can have profound effects on cellular homeostasis and may impact cell survival and proliferation. One mechanism of inhibition involves disrupting the binding of ATF-5 to its target DNA sequences, thereby preventing the transcriptional activation of downstream target genes. This can be achieved through various means, such as small molecule inhibitors that interfere with the DNA-binding activity of ATF-5 or by targeting upstream signaling pathways that regulate ATF-5 expression or activity. Additionally, inhibition of ATF-5 may involve strategies aimed at promoting its degradation or blocking its interaction with co-factors necessary for transcriptional activation. By inhibiting ATF-5, it may be possible to modulate cellular responses to stress and mitigates pathological processes associated with ATF-5 dysregulation, such as cancer progression, neurodegenerative diseases, and metabolic disorders.
