Anti-PRAJA1 antibodies enable researchers to detect and measure the PRAJA1 antigen in biological samples. This target is a reported synonym of the PJA1 gene, which encodes praja ring finger ubiquitin ligase 1. This protein is known to have E2-dependent E3 ubiquitin-protein ligase activity. The human version of PRAJA1 has a canonical amino acid length of 643 residues and a protein mass of 71 kilodaltons, although 3 isoforms have been identified. It is reported to be widely expressed in many tissue types. Other names for this target antigen include E3 ubiquitin-protein ligase Praja-1, RING finger protein 70, and RING-type E3 ubiquitin transferase Praja-1. Some PRAJA1 antibodies may have been used in research and have associated citations. Indicated applications for the antibodies listed below include ELISA, Western Blot, Immunofluorescence, and Immunohistochemistry.
