Anti-KRBOX3 antibodies enable researchers to detect and measure the KRBOX3 antigen in biological samples. This target is a reported synonym of the PRKRIP1 gene, which encodes PRKR interacting protein 1. This protein is known to function in mRNA processing and RNA splicing, among other biological roles. The human version of KRBOX3 has a canonical amino acid length of 184 residues and a protein mass of 21 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus of cells. KRBOX3 is a member of the PRKRIP1 protein family.
