Description:
The Fos protein complex and several Fos-related antigens (FRA) bind specifically to a sequence element referred to as the HeLa cell activator protein 1 (AP-1) binding site. A combination of structural and immunological comparisons has identified the Fos-associated protein (p39) as the protein product of the jun proto-oncogene (c-Jun). The p39/Jun protein is one of the major polypeptides identified in AP-1 oligonucleotide affinity chromatography extracts of cellular proteins. These preparations of AP-1 also contain Fos and several FRA's. Some of these proteins bind to the AP-1 site directly whereas others, like Fos, appear to bind indirectly via protein-protein interactions. Cell-surface stimulation results in an increase in c-fos and c-jun products. Thus, the products of two protooncogenes (and several related proteins), induced by extracellular stimuli, form a complex that associates with transcriptional control elements containing AP-1 sites, thereby potentially mediating the long-term responses to signals that regulate growth control and development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rauscher, F J 3rd -- Cohen, D R -- Curran, T -- Bos, T J -- Vogt, P K -- Bohmann, D -- Tjian, R -- Franza, B R Jr -- CA40512/CA/NCI NIH HHS/ -- CA42564/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1988 May 20;240(4855):1010-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Roche Institute for Molecular Biology, Nutley, NJ 07110.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3130660" target="_blank"〉PubMed〈/a〉
