OX1R Protein, Human, Recombinant (His & SUMOstar)

Moderately selective excitatory receptor for orexin-A and, with a lower affinity, for orexin-B neuropeptide. Triggers an increase in cytoplasmic Ca (2+) levels in response to orexin-A binding. OX1R Protein, Human, Recombinant (His & SUMOstar) is expressed in yeast with N-6xHis-sumostar tag. The predicted molecular weight is 21.4 kDa and the accession number is O43613.
