ADRB1 Blocking Peptide – The purity is >90%,tested by HPLC and MS. Purity

The adrenergic receptors (subtypes alpha 1, alpha 2, beta 1, and beta 2) are a prototypic family of guanine nucleotide binding regulatory protein-coupled receptors that mediate the physiological effects of the hormone epinephrine and the neurotransmitter norepinephrine. Specific polymorphisms in this gene have been shown to affect the resting heart rate and can be involved in heart failure. [provided by RefSeq, Jul 2008]

ADRB1: a GPCR-coupled 7 transmembrane receptor that binds epinephrine and norepinephrine with approximately equal affinity. Mediates the catecholamine-induced activation of adenylate cyclase through the action of G proteins. Interacts with PIST and PSD-95. Localized at the plasma membrane and in the Golgi upon PIST overexpression. Homologous desensitization of the receptor is mediated by its phosphorylation by beta-adrenergic receptor kinase.
