From:Science (Vol. 254, Issue 5036) Peer-ReviewedAMONG THE FUNCTIONS OF Protein degradation in living cells are the elimination of abnormal proteins and the temporal control of many cellular processes that involve short-lived regulators [1]. The metabolic instability...
-
From:Science (Vol. 229) Peer-ReviewedBiochemical differences in aminopeptidase-I (AM-I) allozymes (products of the Lap locus) in the marine mussel Mytilus edulis (1) result in genotypespecific rates of change in the free amino acid (FAA) pool when mussels...

From:Science (Vol. 244, Issue 4902) Peer-ReviewedTwo Molecular Transitions Influence Cardiac Sodium Channel Gating VOLTAGE-DRIVEN CONFORMATIONAL changes that control the opening and closing of Na.sup.+ channels form the molecular basis for membrane excitability....
-
From:Science (Vol. 244, Issue 4902) Peer-ReviewedOxidation-Reduction and the Molecular Mechanism of a Regulatory RNA-Protein Interaction THE FORMATION OF SPECIFIC NUcleic acid-protein complexes has been shown to play a key role in DNA transcription, pre-mRNA...
-
From:Science (Vol. 270, Issue 5233) Peer-ReviewedThe activation of cyclin-dependent kinases (CDKs) requires the phosphorylation of a conserved threonine ([Thr.sup.160] in Cdk2) by CDK-activating kinase (CAK). Human KAP (also called Cdi1), a CDK-associated phosphatase,...
-
From:Science (Vol. 277, Issue 5331) Peer-ReviewedIn response to DNA damage, mammalian cells prevent cell cycle progression through the control of critical cell cycle regulators. A human gene was identified that encodes the protein Chk1, a homolog of the...

From:Journal of Clinical Investigation (Vol. 125, Issue 11) Peer-ReviewedPolarized activation of adipose tissue macrophages (ATMs) is crucial for maintaining adipose tissue function and mediating obesity-associated cardiovascular risk and metabolic abnormalities; however, the regulatory...
-
From:Science (Vol. 278, Issue 5338) Peer-ReviewedBAD is a distant member of the Bc1-2 family that promotes cell death. Phosphorylation of BAD prevents this. BAD phosphorylation induced by interleukin-3 (IL-3) was inhibited by specific inhibitors of phosphoinositide...
-
From:Nature (Vol. 455, Issue 7209) Peer-ReviewedEpac proteins are activated by binding of the second messenger cAMP and then act as guanine nucleotide exchange factors for Rap proteins (1,2). The Epac proteins are involved in the regulation of cell adhesion 3 and...

From:Journal of Clinical Investigation (Vol. 128, Issue 9) Peer-ReviewedNonalcoholic fatty liver disease (NAFLD) is a global epidemic in obese children and adults, and the onset might have fetal origins. A growing body of evidence supports the role of developmental programming, whereby the...
-
From:Science (Vol. 296, Issue 5572) Peer-ReviewedA central problem in biology is determining how genes interact as parts of functional networks. Creation and analysis of synthetic networks, composed of well-characterized genetic elements, provide a framework for...
