Beta-1 adrenergic receptor. The beta-1 adrenergic receptor (β 1 adrenoceptor), also known as ADRB1, can refer to either the protein-encoding gene (gene ADRB1) or one of the four adrenergic receptors. [ 5 ] It is a G-protein coupled receptor associated with the Gs heterotrimeric G-protein that is expressed predominantly in cardiac tissue.
The adrenergic receptors or adrenoceptors are a class of G protein-coupled receptors that are targets of many catecholamines like norepinephrine (noradrenaline) and epinephrine (adrenaline) produced by the body, but also many medications like beta blockers, beta-2 (β 2) agonists and alpha-2 (α 2) agonists, which are used to treat high blood ...
Beta-blockade of the β 1 receptor will inhibit cAMP from phosphorylating, and it will decrease the ionotrophic and chronotropic effect. Note that drugs may be cardioselective, or act on β 1 receptors in the heart only, but still have instrinsic sympathomimetic activity. Acebutolol (has intrinsic sympathomimetic activity, ISA) [80] Atenolol [80]
Glucagon-like peptide-1 receptor. The glucagon-like peptide-1 receptor (GLP1R) is a G protein-coupled receptor (GPCR) found on beta cells of the pancreas and on neurons of the brain. It is involved in the control of blood sugar level by enhancing insulin secretion.
Domains. InterPro. Calcitonin gene-related peptide (CGRP) is a member of the calcitonin family of peptides consisting of calcitonin, amylin, adrenomedullin, adrenomedullin 2 (intermedin) and calcitonin‑receptor‑stimulating peptide. Calcitonin is mainly produced by thyroid C cells whilst CGRP is secreted and stored in the nervous system. [1]
Adrenaline is a nonselective agonist of all adrenergic receptors, including the major subtypes α 1, α 2, β 1, β 2, and β 3. [74] Adrenaline's binding to these receptors triggers a number of metabolic changes.
The thyroid hormone receptor (TR) [1] is a type of nuclear receptor that is activated by binding thyroid hormone. [2] TRs act as transcription factors, ultimately affecting the regulation of gene transcription and translation. These receptors also have non-genomic effects that lead to second messenger activation, and corresponding cellular ...
Alpha-1 adrenergic receptor. alpha-1 (α1) adrenergic receptors are G protein-coupled receptors (GPCRs) associated with the G q heterotrimeric G protein. α 1 -adrenergic receptors are subdivided into three highly homologous subtypes, i.e., α 1A -, α 1B -, and α 1D -adrenergic receptor subtypes. There is no α 1C receptor.
