The protein kinase inhibitor 2-aminopurine (2AP) blocks the induction of the human beta-interferon gene by virus or poly(I)-poly(C) at the level of transcription. This inhibition is specific, since 2AP does not inhibit induction of either the hsp70 heat-shock gene by high temperature or the metallothionein gene by cadmium or dexamethasone. However, 2AP does block the induction of the c-fos and c-myc proto-oncogenes by serum growth factors or virus, suggesting that a protein kinase may be involved in the regulation of these genes, as well as of the beta-interferon gene. However, different factors must be required for the induction of these three genes, since they are not coordinately regulated by the same inducers in most of the cell lines examined.

D011518 Proto-Oncogene Proteins Products of proto-oncogenes. Normally they do not have oncogenic or transforming properties, but are involved in the regulation or differentiation of cell growth. They often have protein kinase activity. Cellular Proto-Oncogene Proteins,c-onc Proteins,Proto Oncogene Proteins, Cellular,Proto-Oncogene Products, Cellular,Cellular Proto Oncogene Proteins,Cellular Proto-Oncogene Products,Proto Oncogene Products, Cellular,Proto Oncogene Proteins,Proto-Oncogene Proteins, Cellular,c onc Proteins
D011519 Proto-Oncogenes Normal cellular genes homologous to viral oncogenes. The products of proto-oncogenes are important regulators of biological processes and appear to be involved in the events that serve to maintain the ordered procession through the cell cycle. Proto-oncogenes have names of the form c-onc. Proto-Oncogene,Proto Oncogene,Proto Oncogenes
