c-Fos Activated Phospholipid Synthesis Is Required for Neurite Elongation in Differentiating PC12 CellsD⃞

Pecchio, Adolfo Alfonso; Gil, Germán A.; Portal, Maximiliano M.; Bussolino, Daniela F.; Renner, Marianne L.; Caputto, Beatriz L.

We have previously shown that c-Fos activates phospholipid synthesis through a mechanism independent of its genomic AP-1 activity. Herein, using PC12 cells induced to differentiate by nerve growth factor, the genomic effect of c-Fos in initiating neurite outgrowth is shown as distinct from its nonge...

The Vaccinia Virus 14-Kilodalton (A27L) Fusion Protein Forms a Triple Coiled-Coil Structure and Interacts with the 21-Kilodalton (A17L) Virus Membrane Protein through a C-Terminal α-Helix

Serrano, Luis; Vázquez, María-Isabel; Cregut, David; Rivas, German; Esteban, Mariano

The vaccinia virus 14-kDa protein (encoded by the A27L gene) plays an important role in the biology of the virus, acting in virus-to-cell and cell-to-cell fusions. The protein is located on the surface of the intracellular mature virus form and is essential for both the release of extracellular enve...
