Description
|
The transcription factor ATF-2 (also called CRE-BP1) binds to both AP-1 and CRE DNAresponse elements and is a member of the ATF/CREB family of leucine zipper proteins. ATF-2 interacts with a variety of viral oncoproteins and cellular tumor suppressors and is atarget of the SAPK/JNK and p38 MAP kinase signaling pathways. Various forms of cellularstress, including genotoxic agents, inflammatory cytokines and UV irradiation, stimulatethe transcriptional activity of ATF-2. Cellular stress activates ATF-2 by phosphorylation ofThr69 and Thr71. Both SAPK and p38 MAPK have been shown to phosphorylate ATF-2 atthese sites in vitro and in cells transfected with ATF-2. Mutations of these sites result in theloss of stress-induced transcription by ATF-2. In addition, mutations at these sites reducethe ability of E1A and Rb to stimulate gene expression via ATF-2.
