Anti-5-hydroxytryptamine (serotonin) receptor 3C, ionotropic antibodies enable researchers to detect and measure the 5-hydroxytryptamine (serotonin) receptor 3C, ionotropic antigen in biological samples. This target is a reported synonym of the HTR3C gene, which encodes 5-hydroxytryptamine receptor 3C. This protein is known to function in chemical synaptic transmission and signal transduction pathways, among other biological roles. The human version of 5-hydroxytryptamine (serotonin) receptor 3C, ionotropic has a canonical amino acid length of 447 residues and a protein mass of 50.2 kilodaltons. It is reported to be localized in the cell membrane of cells. Other names for this target antigen include 5-HT3-C, 5-HT3C, and 5-hydroxytryptamine (serotonin) receptor 3, family member C.
