Cell survival is determined by a balance among signaling cascades, including those that recruit the Akt and JNK pathways. Here we describe a novel interaction between Akt1 and JNK interacting protein 1 (JIP1), a JNK pathway scaffold. Direct association between Akt1 and JIP1 was observed in primary neurons. Neuronal exposure to an excitotoxic stimulus(More)
Site-specific chromosome breakage occurs in many ciliated protozoa during nuclear differentiation. We have determined the cis-acting sequence that controls this process in Tetrahymena thermophila. The Tetrahymena ribosomal RNA gene is bounded by two breakage sites. Injection of this gene into developing macronuclei leads to breakage at these sites. Deletion(More)
Globin gene switching is a well-described model of eucaryotic developmental control. In the case of the human alpha-globin gene cluster, migration of erythropoietic activity from the embryonic yolk sac to the fetal liver is parallaled by the zeta-globin gene silencing and enhanced expression of the alpha-globin genes. To map critical cis determinants of(More)
