A network of substrates of the E3 ubiquitin ligases MDM2 and HUWE1 control apoptosis independently of p53.
(Sci Signal, 2013-05-07)In the intrinsic pathway of apoptosis, cell-damaging signals promote the release of cytochrome c from mitochondria, triggering activation of the Apaf-1 and caspase-9 apoptosome. The ubiquitin E3 ligase MDM2 decreases the ... -
A selective inhibitor of eIF2alpha dephosphorylation protects cells from ER stress.
(Science (New York, N.Y.), 2005-02)Most protein phosphatases have little intrinsic substrate specificity, making selective pharmacological inhibition of specific dephosphorylation reactions a challenging problem. In a screen for small molecules that protect ... -
Phosphorylation/dephosphorylation of the beta-adrenergic receptor regulates its functional coupling to adenylate cyclase and subcellular distribution.
(Proc Natl Acad Sci U S A, 1986-12)Prolonged exposure of cells or tissues to drugs or hormones such as catecholamines leads to a state of refractoriness to further stimulation by that agent, known as homologous desensitization. In the case of the beta-adrenergic ... -
Targeting phosphorylation of eukaryotic initiation factor-2α to treat human disease.
(Progress in molecular biology and translational science, 2012-01)The unfolded protein response, also known as endoplasmic reticulum (ER) stress, has been implicated in numerous human diseases, including atherosclerosis, cancer, diabetes, and neurodegenerative disorders. Protein misfolding ... -
The G-protein-coupled receptor phosphatase: a protein phosphatase type 2A with a distinct subcellular distribution and substrate specificity.
(Proc Natl Acad Sci U S A, 1995-08-29)Phosphorylation of G-protein-coupled receptors plays an important role in regulating their function. In this study the G-protein-coupled receptor phosphatase (GRP) capable of dephosphorylating G-protein-coupled receptor ...
