label: Gq/11-coupled serotonin receptor activity
label_lc: gq/11-coupled serotonin receptor activity
description: "Combining with serotonin and transmitting the signal across the membrane by activation of the Gq/11 subunit of an associated cytoplasmic heterotrimeric G protein complex. The Gq/11 subunit subsequently activates phospholipase C and results in an increase in inositol triphosphate (IP3) levels."
