| + | == Function == | ||
| + | [[http://www.uniprot.org/uniprot/ADRB2_HUMAN ADRB2_HUMAN]] Beta-adrenergic receptors mediate the catecholamine-induced activation of adenylate cyclase through the action of G proteins. The beta-2-adrenergic receptor binds epinephrine with an approximately 30-fold greater affinity than it does norepinephrine. [[http://www.uniprot.org/uniprot/LYS_BPT4 LYS_BPT4]] Helps to release the mature phage particles from the cell wall by breaking down the peptidoglycan. | ||

| + | == Publication Abstract from PubMed == | ||
| + | A highly crystallizable T4 lysozyme (T4L) was fused to the N-terminus of the beta(2) adrenergic receptor (beta(2)AR), a G-protein coupled receptor (GPCR) for catecholamines. We demonstrate that the N-terminal fused T4L is sufficiently rigid relative to the receptor to facilitate crystallogenesis without thermostabilizing mutations or the use of a stabilizing antibody, G protein, or protein fused to the 3rd intracellular loop. This approach adds to the protein engineering strategies that enable crystallographic studies of GPCRs alone or in complex with a signaling partner. | ||
