Anti-5-HT1F antibodies enable researchers to detect and measure the 5-HT1F antigen in biological samples. This target is a reported synonym of the HTR1F gene, which encodes 5-hydroxytryptamine receptor 1F. This protein is known to function in chemical synaptic transmission, among other biological roles. The human version of 5-HT1F has a canonical amino acid length of 366 residues and a protein mass of 41.7 kilodaltons. It is reported to be localized in the cell membrane of cells. This target antigen may also be known as 5HT6.
