Anti-POM121A antibodies enable researchers to detect and measure the POM121A antigen in biological samples. This target is a reported synonym of the POM121 gene, which encodes POM121 transmembrane nucleoporin. This protein is an important component of the nuclear pore complex (NPC). The human version of POM121A has a canonical amino acid length of 1249 residues and a protein mass of 127.7 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the nucleus and ER of cells and widely expressed in many tissue types. This target antigen may also be known as P145.
