leucokinin-like peptide receptor from tick and related proteins, member of the class A family of seven-transmembrane G protein-coupled receptors
This subgroup includes a leucokinin-like peptide receptor from the Southern cattle tick, Boophilus microplus, a pest of cattle world-wide. Leucokinins are invertebrate neuropeptides that exhibit myotropic and diuretic activity. This receptor is the first neuropeptide receptor known from the Acari and the second known in the subfamily of leucokinin-like peptide G-protein-coupled receptors. The other known leucokinin-like peptide receptor is a lymnokinin receptor from the mollusc Lymnaea stagnalis.
Comment:based on the structures of some class A family members with bound ligands (peptides or chemicals), agonists, or antagonists
Comment:Small-molecule chemical ligands tend to bind deeper within the receptor core, compared to a peptide ligand neurotensin, which binds towards the extracellular surface of its receptor.
