Cytokine-activated receptors initiate intracellular signaling by recruiting protein kinases that phosphorylate the receptors on tyrosine residues, thus enabling docking of SH2 domain-bearing activating factors. Here we report that in response to type 1 interferon (IFNα), IFNα receptors recruit cytoplasmic CREB-binding protein (CBP). By binding to IFNαR2 within the region where two adjacent proline...
Phosphatidylinositol 4 phosphate [PI(4)P] is essential for secretion in yeast, but its role in mammalian cells is unclear. Current paradigms propose that PI(4)P acts primarily as a precursor to phosphatidylinositol 4,5 bisphosphate (PIP2), an important plasma membrane regulator. We found that PI(4)P is enriched in the mammalian Golgi, and used RNA interference (RNAi) of PI4KIIα, a Golgi resident phosphatidylinositol...
Cryptochrome blue light photoreceptors share sequence similarity to photolyases, flavoproteins that mediate light-dependent DNA repair. However, cryptochromes lack photolyase activity and are characterized by distinguishing C-terminal domains. Here we show that the signaling mechanism of Arabidopsis cryptochrome is mediated through the C terminus. On fusion with β-glucuronidase (GUS), both the Arabidopsis...
