Summary: Enables octopamine receptor activity. Involved in several processes, including G protein-coupled receptor signaling pathway; positive regulation of circadian sleep/wake cycle, wakefulness; and positive regulation of ovulation. Predicted to be located in membrane. Predicted to be active in dendrite and plasma membrane. Is expressed in several structures, including aminergic neurons; brain; epithelial tube; synaptic neuropil domain; and synaptic neuropil subdomain.
