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.
There are two main groups of adrenoreceptors, α and β, with 9 subtypes in total: α receptors are subdivided into α 1 (a G q coupled receptor) and α 2 (a G i coupled receptor) [ 7 ] α 1 has 3 subtypes: α 1A, α 1B and α 1D[ a ] α 2 has 3 subtypes: α 2A, α 2B and α 2C. β receptors are subdivided into β 1, β 2 and β 3.
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 ...
The beta-2 adrenergic receptor (β 2 adrenoreceptor), also known as ADRB2, is a cell membrane-spanning beta-adrenergic receptor that binds epinephrine (adrenaline), a hormone and neurotransmitter whose signaling, via adenylate cyclase stimulation through trimeric G s proteins, increases cAMP, and, via downstream L-type calcium channel interaction, mediates physiologic responses such as smooth ...
Thyroid hormone receptor beta (TR-beta) also known as nuclear receptor subfamily 1, group A, member 2 (NR1A2), is a nuclear receptor protein that in humans is encoded by the THRB gene. [ 5 ] [ 6 ] Function
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.
Integrin beta 1. Integrin beta-1 (ITGB1), also known as CD29, is a cell surface receptor that in humans is encoded by the ITGB1 gene. [5] This integrin associates with integrin alpha 1 and integrin alpha 2 to form integrin complexes which function as collagen receptors. It also forms dimers with integrin alpha 3 to form integrin receptors for ...
TGF beta receptor 1. Transforming growth factor beta receptor I (activin A receptor type II-like kinase, 53kDa) is a membrane-bound TGF beta receptor protein of the TGF-beta receptor family for the TGF beta superfamily of signaling ligands. TGFBR1 is its human gene.
