The 5-HT4 ELISA kits listed below are analytical tools for measuring concentrations of 5-HT4 in various samples. 5-HT4 is an alternative name for the human HTR4 gene, which encodes the protein, 5-hydroxytryptamine receptor 4. It has been mentioned that 5-HT4 plays a role in chemical synaptic transmission and GPCR signaling pathways, among other functions. Structurally, the HTR4 protein is 388 amino acid residues in length and 43.8 kilodaltons in mass. However, as many as 9 protein isoforms have been identified. It is localized to the cell membrane of the cell. This protein is known to be glycosylated. Other names for this target antigen include 5-HT4R and 5-hydroxytryptamine (serotonin) receptor 4, G protein-coupled.
