Review: Dystroglycan in the Nervous System [PDF]
, 2007 Dystroglycan is part of a large complex of proteins, the dystrophin-glycoprotein complex, which has been implicated in the pathogenesis of muscular dystrophies for a long time.

Spin parity and broken symmetry in finite spin-1/2 chains with frustrated exchange: quantum transition from high to low spin [PDF]
Phys. Rev. B 85, 144415 (2012), 2012 Exact diagonalization of finite spin-1/2 chains with periodic boundary conditions is applied to the ground state (gs) of chains with ferromagnetic (F) exchange $J_1 < 0$between first neighbors, antiferromagnetic (AF) exchange $J_2 = \alpha J_1 > 0$between second neighbors, and axial anisotropy $0 \le \Delta \le 1$. In zero field, the gs is in the $S_z =

Biochemical Journal, 1989 The effect of activation of the alpha-subunit(s) of the stimulatory guanine-nucleotide-binding protein, Gs, on levels of this polypeptide(s) associated with the plasma membrane of L6 skeletal myoblasts was ascertained.

Structure of A=7 iso-triplet $Λ$ hypernuclei studied with he four-body model [PDF]
Phys.Rev.C80:054321,2009, 2009 The structure of the T=1 iso-triplet hypernuclei, $^7_{\Lambda}$He, $^7_{\Lambda}$Li and $^7_{\Lambda}$Be within the framework of an $\alpha +\Lambda +N+N$ four-body cluster model is studied. Interactions between the constituent subunits are determined so as to reproduce reasonably well the observed low-energy properties of the $\alpha N$, $\alpha ...

Differential coupling of G protein alpha subunits to seven-helix receptors expressed in Xenopus oocytes [PDF]
, 1994 Xenopus oocytes were used to examine the coupling of the serotonin 1c (5HT1c) and thyrotropin-releasing hormone (TRH) receptors to both endogenous and heterologously expressed G protein alpha subunits.

Molecular Oncology, EarlyView.Circulating tumor DNA (ctDNA) offers a possibility for different applications in early and late stage breast cancer management. In early breast cancer tumor informed approaches are increasingly used for detecting molecular residual disease (MRD) and early recurrence. In advanced stage, ctDNA provides a possibility for monitoring disease progression and

Angewandte Chemie, EarlyView.Benzamide‐directed iridium‐catalyzed branched selective and enantioselective C(sp2)‐H additions to minimally activated alkenes give tertiary and quaternary benzylic stereocenters under byproduct‐free conditions. The processes are enabled by a family of SPINOL‐based homochiral diphosphonite ligands.

G protein beta gamma subunits synthesized in Sf9 cells. Functional characterization and the significance of prenylation of gamma [PDF]
, 1992 Heterotrimeric guanine nucleotide-binding regulatory proteins (G proteins) consist of a nucleotide-binding alpha subunit and a high- affinity complex of beta and gamma subunits.

Functional selectivity of GPCR-directed drug action through location bias. [PDF]
, 2017 G-protein-coupled receptors (GPCRs) are increasingly recognized to operate from intracellular membranes as well as the plasma membrane. The β 2 -adrenergic GPCR can activate G s -linked cyclic AMP (G s -cAMP) signaling from endosomes.

Biochemical Journal, 1992 Neuroblastoma x glioma hybrid NG108-15 cells express a high-affinity IP prostanoid receptor. Saturation binding analysis of this receptor, using [3H]prostaglandin E1 ([3H]PGE1) as ligand, indicated that it was present at some 1.5 pmol/mg of membrane ...
