Anti-GTPCH1 antibodies enable researchers to detect and measure the GTPCH1 antigen in biological samples. This target is a reported synonym of the GCH1 gene, which encodes GTP cyclohydrolase 1. This protein is known to function in the assembly of protein complexes, among other biological roles. The human version of GTPCH1 has a canonical amino acid length of 250 residues and a protein mass of 27.9 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells and notably expressed in many tissues, such as the cervix, vagina, and adrenal gland. Other names for this target antigen include DYT14, DYT5, and DYT5a. Indicated applications for GTPCH1 antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
