Regulation of the rat cardiac troponin I gene by the transcription factor GATA-4.
Troponin I is a thin-filament contractile protein expressed in striated muscle. There are three known troponin I genes which are expressed in a muscle-fibre-type-specific manner in mature animals. Although the slow skeletal troponin I isoform is expressed in fetal and neonatal heart, the cardiac isoform is restricted in its expression to the myocardium at all developmental stages. To study the ...
متن کاملOn homology modeling of the M2 muscarinic acetylcholine receptor subtype
Twelve homology models of the human M2 muscarinic receptor using different sets of templates have been designed using the Prime program or the modeller program and compared to crystallographic structure (PDB:3UON). The best models were obtained using single template of the closest published structure, the M3 muscarinic receptor (PDB:4DAJ). Adding more (structurally distant) templates led to wor...
متن کاملExpression of functional M2 muscarinic acetylcholine receptor in Escherichia coli.
The M2 muscarinic acetylcholine receptor mutant (M2 mutant), with a lack of glycosylation sites, a deletion in the central part of the third inner loop, and the addition of a six histidine tag at the C-terminus, was fused to maltose binding protein (MBP) at its N-terminus and expressed in Escherichia coli. The expression level was 0.2 nmol receptor per 100 ml culture, as assessed as [3H]L-quinu...
متن کاملNon-Neuronal Functions of the M2 Muscarinic Acetylcholine Receptor
Acetylcholine is an important neurotransmitter whose effects are mediated by two classes of receptors. The nicotinic acetylcholine receptors are ion channels, whereas the muscarinic receptors belong to the large family of G protein coupled seven transmembrane helix receptors. Beyond its function in neuronal systems, it has become evident that acetylcholine also plays an important role in non-ne...
متن کاملDualsteric modulators of the M2 muscarinic acetylcholine receptor
G-protein coupled receptors (GPCRs) trigger multiple signal-switching mechanisms like binding of ß-arrestin proteins, activation of kinases and G-protein activation [1]. The poor understanding of the conformational changes resulting in these activations is a major challenge for the design of specific GPCR modulating drugs. For the muscarinic M2 receptor, allosteric, orthosteric and dualsteric b...
