NTSR1

NTSR1, a human GPCR binding the neurotransmitter neurotensin, is our latest addition to our portfolio of purified GPCRs, which also includes GLP1 receptor 1, G-protein coupled bile receptor 1 (TGR5), and mu-opioid receptor 1, reconstituted in nanodisc.

The protein is available off-the shelf, ready for ligand binding studies, crystallization, and other biochemical/biophysical experiments.
