Anti-POC20 antibodies enable researchers to detect and measure the POC20 antigen in biological samples. This target is a reported synonym of the UBA1 gene, which encodes ubiquitin like modifier activating enzyme 1. This protein is known to function in DNA damage pathways and protein ubiquitination, among other biological roles. The human version of POC20 has a canonical amino acid length of 1058 residues and a protein mass of 117.8 kilodaltons. It is reported to be localized in the nucleus, mitochondria, and cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include A1S9, A1S9T, and A1ST. Some POC20 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
