The first X-ray crystal structure of the mouse serotonin 5-HT3 receptor, a pentameric ligand-gated ion channel, is similar to those of other Cys-loop receptors — though here electron density for part of the cytoplasmic domain, which is important for trafficking, synaptic localization, and modulation by cytoplasmic proteins, but not visible in previous structures, is also described.
