Anti-LEREPO4 antibodies enable researchers to detect and measure the LEREPO4 antigen in biological samples. This target is a reported synonym of the ZC3H15 gene, which encodes zinc finger CCCH-type containing 15. This protein is known to function in cytokine-mediated signaling pathways and protein translation, among other biological roles. The human version of LEREPO4 has a canonical amino acid length of 426 residues and a protein mass of 48.6 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells and widely expressed in many tissue types. LEREPO4 is a member of the ZC3H15/TMA46 protein family.
