Anti-5-HT6R antibodies enable researchers to detect and measure the 5-HT6R antigen in biological samples. This target is a reported synonym of the HTR6 gene, which encodes 5-hydroxytryptamine receptor 6. This protein is known to function in chemical synaptic transmission, among other biological roles. The human version of 5-HT6R has a canonical amino acid length of 440 residues and a protein mass of 47 kilodaltons. It is reported to be localized in the cell membrane of cells. Other names for this target antigen include 5-HT6 and 5-hydroxytryptamine (serotonin) receptor 6, G protein-coupled.
