The gene atf2 is located at human chromosome 2q32. The protein ATF-2 has 505 amino acids. Studies in mice indicate a role for ATF-2 in the development of nervous system and the skeleton. ATF-2 is normally activated in response to signals that converge on stress-activated protein kinases p38 and JNK. ATF-2 phosphorylation in response to treatment of cells with tumor promoter phorbol ester has been demonstrated.
Several studies implicate abnormal activation of ATF-2 in growth and progression of mammalian skin tumors. ATF-2 may mediate oncogenesis caused by mutant Ras protein and regulate maintenance of the aggressive cancer phenotype of some types of epithelial cells.
