Anti-Luc7A antibodies enable researchers to detect and measure the Luc7A antigen in biological samples. This target is a reported synonym of the LUC7L3 gene, which encodes LUC7 like 3 pre-mRNA splicing factor. This protein is known to function in RNA splicing, among other biological roles. The human version of Luc7A has a canonical amino acid length of 432 residues and a protein mass of 51.5 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types. Other names for this target antigen include CRA, CREAP-1, and CROP.
